(c) loss of ₹ 400
From the question it is given that,
Cost price of cow = ₹ 18000
Profit percent on cow = 10%
We know that, Profit percent = (Profit/CP) × 100
10 = (Profit/₹ 18000) × 100
(10 × 18000)/100 = Profit
Profit = 10 × 180
Profit = ₹ 1800
Then, Profit = SP – CP
1800 = SP – 18000
SP = 1800 + 18000
SP of cow = ₹ 19800
Cost price of buffalo = ₹ 44000
He sold the buffalo at a loss of 5%
We know that, Loss percent = (loss/CP) × 100
5 = (loss/44000) × 100
(5 × 44000)/100 = loss
Loss = 5 × 440
Loss = ₹ 2200
Loss = CP – SP
₹2200 = ₹44000 – SP
SP = 44000 – 2200
SP of buffalo = ₹ 41,800
Now,
Total cost price of both buffalo and cow = ₹ 44000 + ₹ 18000
= ₹ 62000
Total selling price of both buffalo and cow = ₹ 41800 + ₹ 19800
= ₹ 61,600
Selling price of both buffalo and cow is less when compare to cost price,
So, Loss = CP – SP
= ₹ 62000 – ₹ 61600
Loss = ₹ 400
