Question

the age of ram and kamal is in the ratio of 5:7 and difference between two is 12 years find the age of ram and kamal

Answer 1

let's ram and Kamal proportional rate=x
ram : Kamal
5x : 7x
difference of their age 12 years
so, 7x-5x=12,2x=12,x=6
Age of ram is 5x=5*6=30years
Age of Kamal is 7x=7*6=42years

Answer 2

let rams age be 5x
let kamals age be 7x
difference between two is 12
so7x-5x is equal to 12
so x is equal to 6
hence age of ram is 30 and age of kamal is 42
