Question

29. At present, the ratio between the ages of A and B is 4:3.
After 6 years, A's age will be 26 years. What is the present
age of B?
a) 11, b) 13 0) 14 d) 15
​

Answer 1

Ratio of ages of A and B = 4:3

Let the A's age be 4x and B's age be 3x

After 6 years A's age = (4x + 6)years

According to the question :

4x + 6 = 26

4x = 26 - 6

4x = 20

x = 20/4

x = 5

B's age = 3x = 3(5) = 15 years

So, B's age is (d)15 years.
