Question

Julie just turned 13 years old. In 7 years, her age will be double her brother Pascal’s age. How old will Pascal be on Julie’s 18th birthday?

Answer 1

8

Explanation:

call Julie J, and call Pascal P.

if Julie is now 13, and in 7 years she will be 13 + 7 = 20. this is double Pascal's age. that means when she is 20, he will be 20/2 = 10. she is 10 years older.

J = P + 10

18 = P + 10

P = 8

Pascal will be 8 years old when Julie is 18
