Question

how to solve this problem

Answer 1

here is your answer.

Answer 2

Amount = Rs 15500

Principal = Rs 12500

Time = 4 years

SI = Amount - Principal

=> SI = 15500 - 12500 = Rs 3000

=> ( P× R× T) /100 = 3000

=> ( 12500 × R × 4) / 100 = 3000

=> 125 × 4 × R = 3000

=> 500 × R = 3000

=> R = 3000 /500

=> R = 6

Rate of interest = 6 p.c.p.a
