A, B, and C are partners with equal profit sharing ratios. Their fixed capitals are ₹30,000, ₹25,000 and ₹30,000 respectively. C decided to take retirement. A and B decided to continue the partnership firm and change their profit sharing ratio to Capital Ratio. What is the gaining Ratio of A and B?

7:4

The correct answer is option 3- 7:4.

Old ratio between A, B, C is 1:1:1

New ratio between A & B is capital ratio means 30,000:25,000 i.e. 6:5

Gain = New share - Old share

Gain of A = 6/11 - 1/3
               = (18-11)/33
               = 7/33

Gain of B = 5/11 - 1/3
               = (15-11)/33
               = 4/33

Gaining ratio = 7/33 :4/33
                     = 7:4
