Step 1: Calculate profit distribution in the existing ratio.
Profit sharing ratio of Abhay : Boris : Chetan = \(5:3:2\)
Total profit = Rs. 2,00,000
Abhay's share \(= \frac{5}{10} \times 2,00,000 = 1,00,000\)
Boris's share \(= \frac{3}{10} \times 2,00,000 = 60,000\)
Chetan's share \(= \frac{2}{10} \times 2,00,000 = 40,000\)
Step 2: Calculate deficiency in Boris's guaranteed profit.
Guaranteed profit to Boris = Rs. 95,000
Actual share received by Boris = Rs. 60,000
\[
\text{Deficiency} = 95,000 - 60,000 = 35,000
\]
Step 3: Distribution of deficiency.
The deficiency is to be borne equally by Abhay and Chetan.
\[
\text{Each partner's share of deficiency} =
\frac{35,000}{2} = 17,500
\]
Step 4: Amount given by Abhay to Boris.
Abhay bears Rs. 17,500 and Chetan bears Rs. 17,500.
Thus, the guaranteed amount given by Abhay to Boris is Rs. 17,500.
Final Answer: Rs. 17,500.
