$let \: the \: common \: ratio \: be \: 3x \: and \: 4x. \\ =4x = 36 \\ = x = \frac{36}{4} \\ x = 9 \\ age \: of \: ramu = 3x \\ = 3 \times 9 \\ = 27years$

Answer 2

Ram's age = 27 years

Given:

The ratio of the ages of Ramu and his elder sister is 3:4

The age of elder sister is 36

To find:

what is the age of Ramu

Solution:

Given ratio of ages of Ramu and his elder sister = 3:4

Let us assume that 3x and 4x be the ages of Ramu and his sister

[ since they are in ratio 3 : 4 ]

Given that Ramu's sister age = 36

⇒ 4x = 36

⇒ x = 36/4

⇒ x = 9

Therefore, x = 9 years

We know that Ramu's age = 3x

⇒ 3x = 3(9) = 27 years

Therefore, Ram's age = 27 years
