​

Answer 1

Answer:

present age of A= 22 years

and Present age of B = 10 years

Answer 2

Answer:

let us Rahim's age = x say

let us Ramoss age = y say

Explanation:

4 year's ago :

Rahim's age = (x-4)

Ramoss age =(y-4)

4 year's ago Rahim's age was 3 times Ramoss age after 2 year's

(x-4)=3(y-4)

x-4=3y-12y

x-3y = -8.........(1)

given that after 2 year's it would be doubt

(x+2)=2(y+2)=2y+4

x-2y=2.........(2)

on solving eq(1) and (2)

x-3y=-8

x-2y=2

-y = -10

y=10

substitute y = 10 in (1) we get

x-3y= -8

x-3(10)=-8

x-30=-8

x=-8+30

x=22

the present age of Rahim's =22

the present age of Ramoss =10
