Answer 2

Answer:

Ans6-- 20years and 28 years

Step-by-step explanation:

Ans 6--

Let the age of Hari is = 5x years

then , the age of Harry is = 7x years

After four years

hari age will be = 5x+4 years

and Harry age will be = 7x+4 years

A.T.Q (5x+4)/(7x+4) = 3/4

(5x+4)*4 = (7x+4)*3

20x+16 = 21x+12

20x-21x = 12-16

-x = -4

x = 4

hence , present age of Hari is = 5*4 = 20 years

and present age of Harry is = 7*4 = 28 years
