Solution

The correct option is A

₹ 36659.7


Time is 2 years and 4 months = 28 months or 213 years
Principal, P = 26400
Rate of interest, r=15%

First we will calculate the compound interest for 2 years

Amount, A=P[1+r100]n
=26400[1+15100]2
=26400[1+320]2
=26400[2320]2
= 34914

Taking this amount as principal, now we will calculate simple interest on ₹ 34914 for 13 years​.

Simple interest, S.I.=34914×15100×13= 1745.7

Therefore, total amount to be paid in order to clear the loan is ₹ 34914 + ₹ 1745.7 = ₹ 36659.7
