Question 1 of 5
1. Question
In 2016, Ritu read 12 English books and 9 Hindi books. In 2017, she read twice as many Hindi books as English books. If 60% of the books that she read during the two years were Hindi, how many books did she read in 2017?
Correct
Solution (c)
Let number of English books Ritu read in 2017 is ‘x’. So, number of Hindi books she read in 2017 will be 2x. Therefore, total books read by her in two years are 21+3x.
A/Q,
60/100 * (21+3x) = 2x +9,
=> 126 + 18x = 20x + 90
=> 36 = 2x which gives x= 18.
So, in 2017 she read 3x which is equal to 54books.

Question 2 of 5
2. Question
Anant has to cover 60km distance. But after travelling 1/3rd the distance, he gets tired so he reduces his speed to 3/4th. Again, he covers the same distance and further reduces his speed to half of the current speed and reaches 30 minutes late. What is the usual speed of Anant?
Correct
Solution (c)
Let his original speed be ‘x’ kmph.
Total time taken = (20/x) + (20/(3/4x)) +(20/(3/8x) = (20/x) + (80/3x) + (160/3x) = 100/x hrs.
Total time he would have taken if he had travelled complete distance at the original speed = 60/x hrs.
A/Q, 100/x – 60/x = ½ hr
40/x = ½ hr
x = 80kmph
Incorrect
Solution (c)
Let his original speed be ‘x’ kmph.
Total time taken = (20/x) + (20/(3/4x)) +(20/(3/8x) = (20/x) + (80/3x) + (160/3x) = 100/x hrs.
Total time he would have taken if he had travelled complete distance at the original speed = 60/x hrs.
A/Q, 100/x – 60/x = ½ hr
40/x = ½ hr
x = 80kmph

Question 3 of 5
3. Question
In an arts college, each student studies exactly one ancient language. Threefifths of the students take Sanskrit’, and onefourth of the remaining students take Ved. If all of the other take Hindi, what per cent of the students take Hindi?
Correct
Solution (d)
We know that 3/5th can be written as 60% or similarly, 1/4th could be written as 25% for any real number.
Number of students studying Sanskrit = 60%
Number of students studying Ved = 25% of remaining 40% which is nothing but 10% of total
So, number of students studying Hindi is remaining 30%.
Incorrect
Solution (d)

Number of students studying Sanskrit = 60%
Number of students studying Ved = 25% of remaining 40% which is nothing but 10% of total
So, number of students studying Hindi is remaining 30%.
