Question

Mira is 10 years older than Abhishek is now, if the sum of their ages now is 35, find her brother’s age

after 15 years.​

Answer 1

let mira age be x and her brother abhishek age be y

hence

x=y+15.

x-y=15 (1)

x+y=35. (2)

solve 1 and 2

we get x=25. y=10

hence mira's brother age is 10 years

after 15 years abhishek age,=10+15=25years
