​

Answer 1

Answer:

present age of Ramesh is 20 years old

present age of Mahesh is 28 years old

Step-by-step explanation:

Let age of Ramesh be 5x

Let age of Mahesh be 7x

After four years,

Ramesh=5x+4=3

Mahesh=7x+4=4

By cross multiplication,

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

20x+16=21x+12

20x-21x=12-16

-x= -4

X=4

Ramesh=5*4=20

Mahesh=7*4=28
