Question

the ratio in the ages of A, B and C six years before was 2:3:5.if the sum of their present ages us168,find their ages

Answer 1

Let the ages of A, B, C be 2x, 3x and 5x.
A.T.Q.
$2x + 3x + 5x = 168$
$= > 10x = 168$
$= > x = 168 \div 10$
$x = 16.8$
$therefore \: \\ their \: ages \: are \\ 2x = 2 \times 16.8 = 33.6 \\ 3x = 3 \times 16.8 = 50.4 \\ 5x = 5 \times 16.8 = 84$
