Question

Present age of Anu and Raj are in the ratio 4 :5.Eight years from now the ratio of their ages will be 5:6. Find their present ages.(please explain in steps)​

Answer 1

let Anu's present age be 4 x

Raj present age be 5x

present ratio =4x/5x

after 8 years their ratio will be

4x+8/5x+8=5/6 (cross multiply)

6(4x+8)=5(5x+8)

24x+ 48 = 25x +40

8=x

therefore Anu's present age is 32 years and raj's present age is 40 years

Answer 2

Step-by-step explanation:

Let the present age of Anu is 4x.Then, the present age of Raj will be 5x

8 years from now,

(4x+8)/(5x+8) = 5/6

24x+48 = 25x+40

24x - 25x = 40 - 48

-x = -8 [ here both the signs are same so - get cancelled ]

x = 8

so, Present age of Anu is 32 years and present age of Raj is 40 years.
