Answer the questions from based on following paragraph.

Preeti, Kabir and Shershah are partners in a firm. Kabir retires from the firm. On his date of retirement, ₹1,00,000 became due to him. Preeti and Shershah promised to pay him in four yearly equal installments plus interest @ 12% p.a. on the unpaid balance every year at the end of the year, to which he agreed.

Gaining ratio among remaining partners Preeti and Shershah is:

1:1

The correct answer is option 2- 1:1.

As no information is given about profit sharing ratio, So profit is shared equally (1:1:1) i.e. old ratio.

The gaining ratio of the remaining partners will be the same as the old profit sharing ratio among them and there is no need to compute the gaining ratio. 

So, gaining ratio is 1:1.
