Question

the ratio of the ages of Tina and Rakesh is 9:10 respectivally.what us the present age of Rakesh pls guys answer this question and please explain how to do this question​

Answer 1

Answer:

Given :

The ratio of the ages of Tina and Rakesh = 9:10

As we know , we have to find the present ages .

So, Let us consider the age of Tina and rakesh as 9x, 10x.

Frist, let us see their age 10 years ago:

Tina's age will be = 9x - 10 .

Rakesh age will be 10x - 10 .

(Here we have subtracted 10 , because if the age of both of present will be 9x and 10x what will be 10 years before so we have subtracted 10 ) .

So , the ratio of their age of 10 years ago will be 4:5

According to the question:

$\frac{9x - 10}{10x - 10}$

$45x - 50 = 40x - 40$

$45x - 40x = - 40 + 50$

$5x = 10$

$x = \frac{10}{5}$

$x = 2$

so, the present age of the rakesh will be = 10x = 10(2)

After solving it we will get the present age of rakesh = 20 years.

Hence, the present age of the rakesh = 20 years.
