Question

The ages of Misha and Kamal are in the ratio of 4 : 3 respectively. After 9 years the ratio of their ages will be 7 : 6. What is the difference in their present ages?

• A. 2
• B. 13
• C. 12
• D. 3

Answer 1

Answer:

D. 3

The ratio of ages of Misha and Kamal = 4 : 3

After 9 years

Ratio of ages of Misha and Kamal= 7 : 6

$\frac{(4x + 9)}{(3x +9)} = \frac76$

$6\times(4x + 9) = 7\times(3x + 9)$

$24x + 54 = 21x + 63$

$3x = 9$

$x = \frac93= 3$

Misha= 4x = 12

Kamal= 3x = 9

Difference between their present age= 3
