Rohit and Mohit are partners in a firm sharing profits in the ratio of 5:3. They admitted Bijoy as a new partner for 1/7th share in the profit. The new profit sharing ratio will be 4:2:1. What will be the sacrificing ratio of Rohit and Mohit?

3:5

The correct answer is Option (1) → 3:5.

Old ratio = 5:3 (Rohit and Mohit)
Bijoy admitted with 1/7th share
New ratio = 4:2:1 (Rohit, Mohit & Bijoy)

Sacrificed share = Old share - New share

Sacrificed share of Rohit = 5/8 - 4/7
                                    = (35-32)/56
                                    = 3/56

Sacrificed share of Mohit = 3/8 - 2/7
                                    = (21-16)/56
                                    = 5/56

Sacrificing ratio = 3/56 :5/56
                       = 3:5
