The sum of three numbers is 124. If the ratio between the first and the second is 2:3 and between the second and the third is 7:9, then the third number is:

A48

B54 ✓ Correct

C64

D66

Correct answer: (B) 54

Explanation

The third number is 54.

Make the second common: 2:3 = 14:21 and 7:9 = 21:27.

Combined ratio is 14 : 21 : 27, summing to 62.

Total 124 = 2 x 62, so each part doubles.

Third = 27 x 2 = 54.
