Kamala borrowed ₹26,400 from a bank …

Principal (P) = Rs26,400 Rate (R) = 15% per annum Number of years (n) = 2124​ The amount for 2 years and 4 months can be calculated by first calculating the amount for 2 years using the compound interest formula, and then calculating the simple interest for 4 months on the amount obtained at the end of 2 years. For calculating amount of first 2 years, Amount = Principal(1+100R​)Time Interest = Amount - Principal Amount = 26400(1+10015​)2 Amount=34914 Now, the interest for next 31​ years will be calculated using Simple Interest S.I. = 100(P×R×T)​ S.I. = 10034914×15×31​​ S.I. = 1745.70 Therefore, total amount to be paid after 2 years and 4 months = 34,914+1,745.70=Rs 36,659.70 Nearest whole number to 36659.70 is 36660.

Please answer anyone!!
