Questions and Answers

Q 1 - The ages of Arzoo and Arnav are in the ratio of 11:13 respectively. After 7 years the ratio of their ages will be 20:23. What is the difference in years between their ages?

A - 4 years

B - 7 years

C - 6 years

D - 5 years

Answer : C

Explanation

Let the present ages of Arzoo and Arnav be 11x and 13x respectively.
According to the question,
(11x + 7) / (13x + 7) = 20/23
Or, 26x + 140 = 253x + 161
Or, 260x - 253x = 161 - 140
Or, 7x = 21
Or, x =  3

Difference between  their ages = 13x - 11x
= 2x
= 2*3
=  6 years

A - 48 years

B - 42 years

C - 43 years

D - 38 years

Answer : A

Explanation

Let the present ages of Radha and Sudha be x years and y tears respectively.
Five years ago, Radha's age = (x - 5) years
Sudha's age = (y - 5) years
According to the question,
x/y = 7/9
Or,  x= 7y/9  ... (i)
Also, (x - 5) / (y - 5) = 3/4
Or, 4x - 20 = 3y - 15
Or, 4x - 3y = 5 ...(ii)
Putting the value of x from equ (i) into equ (ii),
(4*7y)/9 - 3y = 5
Or, 28y - 27y = 45
Or, y = 45
Therefore, Sudha's age after 3 years = 45 + 3 = 48 years
