Question 53

If a : b = 5 : 8 and c : b = 4 : 3, then a : b : c is equal to:

Solution

a:b = 5:8 ------------------(1)

c:b = 4:3 -> b:c=3:4 ------(2)

LCM of 8 & 3 = 24

Multiply (1) with 3 and (2) with 8

a:b = 15:24 and b:c=24:32

a:b:c = 15:24:32

So , the answer would be Option a)15 : 24 : 32 .
