Question
The sum of three numbers is 147. If the ratio of the
first to the second is 2:3 and that of second to the third is 5:8 then the second number is?ÂSolution
Let the three numbers be A, B and C. Now, A:B = 2:3 & B:C = 5:8 A: B: C = 10:15:24 A+B+C = 147 10k + 15k + 24k = 147 49k = 147 k = 3 Second number = B = 15 x 3 = 45
