The initial profit sharing ratio is:
Kumar : Lakshya : Manoj : Naresh = 3 : 2 : 1 : 4
Total parts = 10
Individual shares:
- Kumar = 3/10
- Lakshya = 2/10
- Manoj = 1/10
- Naresh = 4/10
When Kumar retires, his share of 3/10 is acquired by Lakshya and Manoj in the ratio 3:2.
Share gained by Lakshya = 103×53=509
Share gained by Manoj = 103×52=506
Share gained by Naresh = 0 (since only Lakshya and Manoj acquired Kumar's share)
Gaining Ratio = Lakshya : Manoj : Naresh
= 509:506:0
= 9 : 6 : 0
= 3 : 2 : 0
The gaining ratio represents only the additional share acquired by partners when a partner retires. Since Naresh didn't gain anything from Kumar's share, his gain is 0 in the gaining ratio.
