Question

Sarun is thrice as old as his sister Anita. If five years is subtracted from Anita’s age and seven years added to Sarun’s age , then

Sarun will be five times Anita’s age. How old were they three years ago?

Answer 1

Anita is 11 years old and sarun 55 years old( not so sure about this answer... what do you think)

Explanation:

let Anita's age be x

and sarun's age be 3x

if, x-5 = 3x+7

3x+7 = 5(x-5)

3x+7=5x-25

32=2x

x=16

their ages 3 years ago,

Anita= 16-5=11yrs

sarun= 3*16+7 = 55yrs
