There are 3 brothers Adam Ben and Callum Callum is 3/8 of adams age Ben is 4/5 of Adams age given that Callum is 2 years younger than Ben find Adams age

Respuesta :

Let x =  Adam's age.

Callum is 3/8 of Adam's age.
Therefore Callum's age is (3/8)x.

Ben is 4/5 of Adam's age.
Therefore Ben's age is (4/5)x.

Callum is 2 years younger than Ben, therefore
(3/8)x = (4/5)x - 2
Multiply through by 40.
15x = 32x - 80
-17x = -80
x = 4.706

Adam's age is 4 years, 0.706*12 months = 4 years, 8.5 months

Answer: 4 years, 8.5 months
