Options- A. 15
- B. 25
- C. 35
- D. 45
- Correct Answer
- 35
ExplanationLet A's age 10 years ago = x years.
Then, B's age 10 years ago = 2x years.
(x + 10) / (2x+ l0) = 3/4
=> x = 5.
So, the total of their present ages =(x + 10 + 2x + 10)
= (3x + 20) = 35 years. - 1. If Raj was one-third as old as Rahim 5 years back and Raj is 17 years old now, How old is Rahim now?

Correct Answer: 6:5
Explanation:
Let, Maala?s age = 4A and Kala?s age = 3A
Then 4A + 3A = 28
A = 4
Maala?s age = 16 years
and Kala?s age = 12 years
Proportion of their ages after 8 is = (16 + 8) : (12 + 8)
= 24 : 20
= 6 : 5
Correct Answer: 15
Explanation:
Krish?s age = 3A and Vaibhav?s age = 5A
(3A+9)/(5A+9) = 3/4
=> 4 (3A + 9) = 3 (5A + 9)
=> A = 3
Therefore, Vaibhav?s age = 15 years.
Correct Answer: 22
Explanation:
Let the son's present age be x years. Then, man's present age = (x + 24) years
=> (x + 24) + 2 = 2(x + 2)
=> x + 26 = 2x + 4
So, x = 22
Correct Answer: 4
Explanation:
Let x = the youngest child. Each of the other four children will then be x+3, x+6, x+9, x+12.
We know that the sum of their ages is 50 .
so, x+(x+3)+(x+6)+(x+9)+(x+12) = 50
=> x= 4
The youngest child is 4 years old.
Correct Answer: 15 years
Explanation:
Current ages of Yuvaraj = 4A and Ganguly = 3A
So that 4A + 6 = 26
A = 5
Current age of Ganguly = 3A
=> 3 x 5 = 15 years
Correct Answer: 10
Explanation:
Let Rajeev's present age be x years.
Rajeev's age after 15 years = (x + 15) years.
Rajeev's age 5 years back = (x - 5) years
Then ATQ,
x + 15 = 5 (x - 5)
x + 15 = 5x - 25
=> x = 10
Hence, Rajeev's present age = x = 10 years.
Correct Answer: 45 years
Explanation:
Let, Total of current ages of the 2 daughters is A years.
Then, father?s current age = 3A years.
(3A + 5) = 2 (A +10)
3A + 5 = 2A + 20
A = 15
Therefore, father?s current age = 45 years.
Correct Answer: 40/3 years
Explanation:
Let Rama's age 8 years ago be x years and mother's age 8 years ago be 5x 2(x+16) = 5x+16 2x+32 = 5x=16 3x = 16 x = 16/3 Hence, present age of Rama = x+8 = (16/3)+8 = 40/3 years
Correct Answer: 68
Explanation:
From the given data,
when my age is 24, my mothers age is double of my age
=> 48 yrs is my mothers age
=> Difference is 48 - 24 = 24 years.
When my age is 44
=> My mother is 44 + 24 = 68 years aged.
