Question

The ages of A and B are in the ratio 6 : 5. If the A's age is 18 yrs, find the age of B.

Answer 1

Let the age of A be 6x and the age of B be 5x.

Given, age of A is 18 years.

Therefore,

18 = 6x

or, x = 3

So, the age of B will be (5×3) = 15 years.

Answer 2

Answer:

Let the age of B be x

The ages of A and B are in the ratio of 6 : 5

As per question,

Therefore, 6 : 5 = 18 : x

→ 6 × x = 5 x 18

→ x = $\frac{5 x x}{6} = 15$
