correct answer is: c) ₹ 11200

Explanation

Here,
P = ₹ 12600
R =15% p.a.
T = 3 years
We know, SI =\frac{P\times R\times T}{100}
\therefore SI =\left(\frac{12600\times15\times3}{100}\right)
\rightarrow SI = ₹ 5670
We also know,
Total Amount = (Principal + SI)
\therefore To clear the debit Hari must pay = (₹12600+₹5670)
\rightarrow\ ₹18270
Now,
Hari paid ₹ 7070 and give a goat to clear off the debt.
So, Cost of the goat is = (Total Amount – Cash Payment)
\therefore Cost of the goat is =(₹18270 - ₹7070)
\rightarrow\ ₹ 11200
Ans: Cost of the goat is ₹ 11200.
