Question 3 of 35
3. Question
Consider the following statements about Indian Ocean Dipole (IOD)
- It occurs because of temperature difference in the equatorial region of Indian Ocean from April to May.
- The negative phase of IOD is found to be beneficial for the Indian monsoon.
- The positive phase of IOD is found to be an obstruction for the Indian monsoon.
How many of the above statements are correct?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Correct Incorrect Incorrect Indian Ocean Dipole (IOD) occurs because of temperature difference in the equatorial region of Indian Ocean from April to May. The positive phase of IOD is found to be beneficial for the Indian monsoon. During this phase the Westerly winds weaken along the equator, allowing warm water to move to Africa. Changes in the winds also allow a rise of cool water from the deep ocean in the east. This creates a temperature difference across the tropical Indian Ocean with cooler than normal water in the east and warmer than normal water in the west.
The negative phase of IOD is found to be an obstruction for the Indian monsoon. During this phase westerly winds intensify along the equator, allowing the concentration of warmer waters near Australia. This creates a temperature difference across the tropical Indian Ocean, with warmer than normal water in the east and cooler than normal water in the west. Incorrect

Question 7 of 35
7. Question
Jet Streams are high speed winds located in the upper troposphere. Consider the following statements
- Jet Streams are found in both the Northern and Southern Hemispheres.
- Polar front jet streams are closely related to tropical weather disturbances.
- Sub-Tropical Jet Streams are formed as warm air from the equator moves towards the poles.
How many of the above statements are correct?
Correct
Solution (b)
Statement 1 Statement2 Statement 3 Correct Incorrect Correct The Jet streams located in the upper troposphere (9 – 14 km) are bands of high-speed winds (95-190 km/hr). The two most important types of jet streams are the Polar Jet Streams and the Subtropical Jet Streams. They are found in both the Northern and Southern Hemispheres.
Polar Jet Streams are created when cold air from the Polar Regions meets warmer air from the equator. It is a fact that the so-called polar front jet streams are closely related to the middle latitude weather disturbances. It has no relation with the tropical areas and it is confined to the Frigid Zone. Sub-Tropical Jet Streams are formed as warm air from the equator moves towards the poles that form a steep temperature incline along a subtropical front. Incorrect

Question 8 of 35
8. Question
Consider the Following statements regarding Equatorial Climate:
- Temperature is uniform throughout the year therefore Diurnal range of temperature is large.
- Cloudiness and heavy precipitation make the equatorial climate very humid and sticky.
Choose the correct code:
Correct
Solution (b)
Statement 1 Statement 2 Incorrect Correct The most outstanding feature of the equatorial climate is its great uniformity of temperature throughout the year therefore, the diurnal range of temperature is small. Precipitation is heavy between 60 inches and 100 inches and well distributed throughout the year. There is no month without rain. A distinct dry season like those of the Savanna or the Tropical Monsoon Climates is absent. The Cloudiness and heavy precipitation make relative humidity very high and thus, the climate becomes sticky and uncomfortable.

Question 9 of 35
9. Question
Consider the following statements about mountain climate and coastal climate?
- Unlike coastal climate, mountain climate does not witness much seasonal variation in a single year.
- Temperature inversion is more frequent in coastal climates than in mountain climates.
- Both types of climates are suitable for the growth of coniferous forests.
How many of the above statements are correct?
Correct
Solution (d)
Statement 1 Statement 2 Statement 3 Incorrect Incorrect Incorrect Unlike mountain climate, coastal climate does not witness much seasonal variation in a single year. This is because of the moderation of heat due to the presence of Oceans/seas. On the other hand, Mountain experiences several climatic phenomena like temperature inversion, Katabatic winds in the valleys, etc, and will witness different weather patterns. Temperature inversion is more frequent in the mountainous region because of katabatic winds. Temperature inversion is a reversal of the normal behavior of temperature in the troposphere (the region of the atmosphere nearest the Earth’s surface), in which a layer of cool air at the surface is overlain by a layer of warmer air. (Under normal conditions air temperature usually decreases with height). Coastal climates rarely favor the growth of coniferous forests. A coniferous forest is a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest. In most temperate coniferous forests, evergreen conifers predominate, while some are a mix of conifers and broad-leaf evergreen trees and/or broad-leaf deciduous trees.
Temperate evergreen forests are common in the United States of America, areas of regions that have mild winters and warm summers.
They have needle-pointed leaves that avoid the deposition of snow and help in the process of photosynthesis.

Question 11 of 35
11. Question
Consider the following statements about different Climatic regions of the world
- Savannah Climate is a transitional type of climate found between equatorial forests and trade wind hot deserts.
- Major Hot deserts of the world are located on the west coasts of continents between latitudes 30° and 45°.
- Mediterranean climate is characterized by a dry warm summer with onshore winds.
- Temperate grasslands are found in Sudan-type of climates.
How many of the above statements are correct?
Correct
Solution (a)
Statement 1 Statement 2 Statement 3 Statement 4 Correct Incorrect Incorrect Incorrect Savannah Climate is a transitional type of climate found between equatorial forests and trade wind hot deserts. Grasses and trees – The savanna is a rolling grassland with scattered trees and shrubs.
Rainy and dry seasons – Savannas have two distinct seasons in regard to precipitation. There is a rainy season in the summer with around 15 to 25 inches of rain and a dry season in the winter when only a couple of inches of rain may fall.
Large herds of animals – There are often large herds of grazing animals on the savanna that thrive on the abundance of grass and trees.
Warm – The savanna stays pretty warm all year. It cools down some during the dry season but stays warm and humid during the rainy season.
Major Hot deserts of the world are located on the west coasts of continents between latitudes 15° and 30°. It includes the Sahara Desert and the Great Australian Desert. The climate of these deserts is scorching hot and parched dry. It has a short rainy season. Since the sky is cloudless and clear, the rate of water evaporation is greater than the rate of water accumulation. Hence, there is water scarcity.
However, the nights may be freezing cold with temperatures nearing zero degrees
Celsius. Thus, there is a high diurnal range of temperature.
Mediterranean climate is characterized by a dry warm summer with offshore winds. Almost no rain falls during the summer, so most of the rain falls during the cooler winter. The summer experiences cold ocean currents that bring dry air and no precipitation.
During the winter the currents shift and warmer, moist air brings rain to these areas. Snow can fall in higher elevation areas or places that are farther north.
Mediterranean climates receive around 20 inches of annual(yearly) rainfall.
Temperate grasslands are found in the Temperate zone and not in the tropical zone. Sudan has tropical grasslands and not temperate grasslands. In Eurasia they are called the Steppes, in North America, they are called Prairies, in South America, they are called Pampas, in South Africa, they are called Velds

Jet streams play an important role in:
- Monsoons
- Cyclones
- Anti-cyclones
- Heat balance
Which of the below option is/are correct?
Correct
Solution (d)
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away
As jet streams impact changes in upper atmospheric circulations, they affect all the above phenomenon.

Question 13 of 35
13. Question
Consider the following pairs concerning types of drainage patterns
- Trellis Pattern – It develops where hard and soft rocks exist parallel to each other.
- Rectangular Pattern – It develops when a stream flows in different directions from a central peak.
- Dendritic Pattern – The streams and tributaries’ development resemble the branches of a tree.
- Radial Pattern – It develops when there is an accumulation of streams to a central point from where the river flows downstream.
How many of the pair(s) given above is/are correct?
Correct
Solution (b)
Statement 1 Statement 2 Statement 3 Statement 4 Correct Incorrect Correct Incorrect Trellis Drainage Pattern: When a river is joined by its tributaries at almost right angles, it develops a trellis pattern. Trellis pattern develops where hard and soft rocks exist parallel to each other. Rectangular Drainage Pattern: When rocks are strongly joined, then a rectangular pattern develops. The rectangular drainage pattern is prevalent in faulted areas.
It grows on a rocky surface that is closely bound.
Streams take the path of least resistance; therefore, they congregate in areas with the weakest exposed rock.
The tributary streams bend sharply and enter the mainstream at a steep angle. E.g. Chambal, Betwa, and Ken are three streams found in the Vindhya mountain range.
Dendritic Drainage Pattern: When the river channel follows the slope of the terrain, it develops a dendritic pattern. The stream and its tributaries resemble the branches of a tree. Hence, it is called a dendritic pattern Radial Drainage Pattern: When the streams flow in different directions from a central peak or dome-like structure, a radial pattern is developed. The description given in the question matches the Centripetal system of drainage.

Question 31 of 35
31. Question
A person walks a certain distance and rides back in 61⁄2 hours. If he walks both ways, the time taken is 7(3⁄4) hours. How long would it take if he rides both ways?
Correct
Solution (b)
= W + R = 13/2 ……. (i)
= W + W = 31/4 ……. (ii)
= 2W = 31/4 or W = 31/8
Putting W = 31/8 in equation (i) above
31/8 + R = 13/2
R = 13/2 – 31/8 = (52 – 31)/8 = 21/8
Therefore, 2 R = 2 ×21/8 = 21/4 = 51⁄4 hours = 5 hours 15 minutes

32. Question
In a test, 3 marks are given for each correct answer and 2 marks are cut for each wrong answer. In that test of 50 questions, a student got 60 marks. How many questions did he solve correctly?
Correct
Solution (c)
Let the number of correct questions be ‘x’
Then, wrong questions is “(50-x)”
Therefore, 3x – 2 (50-x) = 60
3x – 100 + 2x = 60 => 5x = 160 => x = 32

Question 33 of 35
33. Question
In a group of persons, 60% of the persons are male and 40% of the persons are married. If two-fifth of the males are married, what fraction of the females is single?
Correct
Solution (b)
Let the no. of total persons = 100
Number of male = 60
∴ No. of female = 100 – 60 = 40
∴ Total married male = (2/5) * 60 = 24
∴ Married female = 40 – 24 = 16
Now, unmarried female = 40 – 16 = 24
∴ Required fraction = 24/40 = 3/5
Incorrect
Solution (b)
Let the no. of total persons = 100
Number of male = 60
∴ No. of female = 100 – 60 = 40
∴ Total married male = (2/5) * 60 = 24
∴ Married female = 40 – 24 = 16
Now, unmarried female = 40 – 16 = 24
∴ Required fraction = 24/40 = 3/5

35. Question
The average height of 40 students is 163 cm. On a particular day three students A, B, C were absent and the average of the remaining 37 students was found to be 162 cm. If A, B have equal heights and the height of C be 2 cm less than that of A, find the height of A?
Correct
Solution (c)
Total height of 40 students = 40 x 163 = 6520
Total height of 37 students = 37 x 162 = 5994
Therefore, Height of three students A, B and C =6520 – 5994 = 526
Let the height of A & B individually be = x
Therefore, Height of C = x – 2
- x+x+x-2 = 526
- 3x = 528 x = 528/3 = 176 cm
