Question

Creflo is 6 years older than Dean.

Raheem is twice as old as Creflo.
The sum of their ages is 34.
Work out the ratio of Dean's age to Creflo's age to Raheem's age.

Answer 1

C = D + 6
R = 2C
D + C + R = 34

R = 2 (D+6)
R = 2D + 12

D + (D + 6) + (2D + 12) = 34
Add like terms.

4D + 18 = 34
4D = 34 - 18
4D = 16
D = 4

C = D + 6
C = 4 + 6
C = 10

R = 2C
R = 2(10)
R = 20

Write as ratio.
D:C:R
4:10:20
