Question

John father is 5 times older than john and john is twice as his sister alex. In 2 years the sum of their age is 58 . How old is john now

Answer 1

Step-by-step explanation:

let john's age be x

john's fathers age = 5x

john's sisters age = x/2

sum of their age is 58

x + 5x + x/2 = 58

7x/2 = 58

7x = 116

x = 16.5
