Given
Camilo is twice as old as Lowen now. 10 years ago, Camilo was four times as old as Lowen
Answer
Let Lowen age be x
Camilo age is 2x
10 years ago
Lowens age = x-10
Camilo age = 2x - 10
A/Q
4(x-10) = 2x - 10
4x - 40 = 2x - 10
4x-2x = 40 - 10
2x = 30
x = 15
Lowens age = 15 years
Camilos age = 2 x 15 = 30 years
