(D) Let the principal amount be $P$.The interest rate for the first year is $6\%$.The interest rate for the second year is $6\% + 1.5\% = 7.5\%$.The interest rate for the third year is $7.5\% + 1.5\% = 9\%$.Since the interest is calculated on the principal $P$ for each year separately:Total Interest = $\frac{P 	imes 6 	imes 1}{100} + \frac{P 	imes 7.5 	imes 1}{100} + \frac{P 	imes 9 	imes 1}{100} = 8190$.$\frac{P}{100} 	imes (6 + 7.5 + 9) = 8190$.$\frac{P}{100} 	imes 22.5 = 8190$.$P = \frac{8190 	imes 100}{22.5}$.$P = \frac{8190000}{225} = 36400$.Therefore,the loan amount is $Rs. 36400$.

Mayuri took a loan at a simple interest rate of $6 \, p.c.p.a.$ in the first year,and the rate increased by $1.5 \, p.c.p.a.$ every year. If she paid $Rs. 8190$ as interest at the end of $3 \, years$,what was her loan amount (in $Rs.$)?
