Answer 1

Ram's age is 12 years and Rahim's age is 10 years

Step-by-step explanation:

let be the present ages of both be 6x and 5 x

after four years ,

the ram's age = 4x +4

the rahim's age = 6x +4

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

= (cross muliple)

=18x+24=20x+20

= 18x-20x = 20-24

=+2x=+4

= X=4/2

= x = 2

the present age will be ,

Rams age =6x= 6*2 = 12 years

rahims age= 5x = 5*2 = 10 years
