Question

Tim’s age is nine more than his sister, Jill. Twice his age added to twice Jill’s age is 330.

Answer 1

jill age is 78 and tim's age is 87

Explanation:

let jill age be x then, tim's age is 9+x

by the question,

2(9+x) + 2x = 330

or,18 + 2x + 2x = 330

or,4x = 330-18

or, x = 312÷4

x = 78

9+x= 9+78=87
