Question

The ratio of ages of a,b and c is 5:8:9 . If the sum of ages of A and C is 56 . Then the age of B

Answer 1

Hey MATE!

Let the angles A,B and C be 5x, 8x and 9x.

The sum of 5x and 9x is 56.


5x + 9x = 56

14x = 56

x = 56/14

x = 4


Therefore the angles are :

5x == 5(4) = 20°
8x == 8(4) = 32°
9x == 9(4) = 36°

Hope it helps

Answer 2

$let \: 5x \: 8x \: and \: 9x \: be \: the \: age \: of \: a \: b \: and \: c \\ we \: have \: 5x + 9x = 56 \\ 14x = 56 \\ x = 4 \\ so \: the \: age \: of \: b \: will \: be \: 8x = 8 \times 4 = 32$
