Question

Jean and John are neighbors. The sum of their ages is 52. How old is John if Jean is 12 years older than him.

Answer 1

john is 20 years old

Explanation:

we can take the ages as

john= x

jean= x+12

according to question

x+(x+12)= 52

2x+12= 52

transpose

2x= 52-12

2x= 40

x= 40/2

x= 20

john= 20

jean= 20+12= 32

therefore john is 20 years old and jean is 32 years old
