Question

Raj is 13 years old. His sister is 10 years old. How old will they be
when their total age is 55 years?
​

Answer 1

raj will be 29 years old and his sister will be 26 years old

Step-by-step explanation:

let the age of raj's sister be x

so raj's age =x+3(as he was 3 years older than his sister)

a/q

their total age is 55 so

x+(x+3) =55

=>2x+3=55

=>2x=55-3

=>2x=52

=> x=52/2= 26

SO AGE OF RAJ'S SISTER WILL BE 26

AGE OF RAJ=26+3=29

I HOPE IT HELP.
