At the admission of C, A and B were sharing profits in the ratio 3:2. The new ratio is 4:3:2. Calculate their sacrificing ratio.

7:3

The correct answer is option 3- 7:3.

Old ratio between A & B = 3:2
C admits
New ratio between A, B & C = 4:3:2

Sacrificed share = Old share - New share

A sacrifice = 3/5 – 4/9
                = (27-20)/45
                = 7/45

B sacrifice = 2/5 – 3/9
                = (18 – 15)/45
                = 3/45

Sacrificing ratio = 7/45 : 3/45
                         = 7:3
