Question

Mr. juan is three times old as his son eric. sum of their ages is 64. how old are they?

Answer 1

Mr Juan is 48 years old and Eric is 16 years old

Explanation:

let Eric's age be x, then his father is 3x ( three times as old as Eric )

the sum of their ages is 64 , that is

x + 3x = 64 ( simplify left side )

4x = 64 ( divide both sides by 4 )

`(4)/(4)` x =
`(64)/(4)` , that is

x = 16

and 3x = 3 × 16 = 48

Mr Juan is 48 and Eric is 16
