**Solution**

__Calculation of New Ratio__

Old Ratio of Kabir and Farid 7 : 3

Kabir sacrifices his share of profit in favour of Jyoti = 210

Farid sacrifices his share of profit in favour of Jyoti = 110

Jyoti’s Share = 210+110 = 310

**New Ratio = Old Share − Share Sacrificed**

Kabir’s New Share = 710-210 = 510

Farid’s New Share = 310-110 = 210**New Profit-Sharing Ratio = 5 : 2 : 3**__Calculation of Sacrificing Ratio__**Since, Kabir and Farid are sacrificing 2/10 share and 1/10 share respectively, therefore the sacrificing ratio becomes 2 : 1.**
