Question

Sohail's mother is seven times older than him. four years from now, she will be four times
as old as sohail will be. what are their present ages?

Answer 1

Answer:

let sohail age be x

mother's age 7x

after 4 years

sohail age x+4

mother's age 7x+4

7x+4=4(x+4)

7x+4=4x+16

7×-4x=16-4

3x=12

×=12÷3=4

sohail age is 4 years

mother's age is 7×4=28
