P, Q and R are partners sharing profits in the ratio of 5 : 4 : 3. Q retires and P and R decide to share future profits equally. Gaining Ratio will be :

05:03 01:03 01:01 03:01

01:03

Old ratio is 5:4:3 New ratio is 1:1 GAINED SHARE= NEW SHARE - OLD SHARE Gain of P=1/2-5/12               =(6-5)12 = 1/12 Gain of R = 1/2-3/12                =(6-3)12 = 3/12 Gaining ratio is = 1/12:3/12                          =1:3
