Question

the age of nishant and sanjay are in the ratio 4:5 . ten years hence , the ratio of their ages will be 6:7. find their present age​

Answer 1

Step-by-step explanation:

Let the ratio of the present ages of Nishant & Sanjay

= 4x : 5x

After 10 years ,

4x+10 / 5x+10 = 6/7

7(4x + 10) = 6(5x + 10)

28x + 70 = 30x + 60

2x = 10

x = 5 years

So , the present age of Nishant = 4(5) = 20 yrs

& the present age of Sanjay = 5(5) = 25 yrs
