Let the sum be Rs. P We know that, C. I. And SI = (P × r × t)/100 Where, P = principal, r = % rate of interest, t = time in years, SI = Simple interest, CI = Compound interest = 44P/100 S.I = P × 20 × 2/100 = 40P/100 According to question, C.I – S.I = Rs. 760 ⇒ P = 760 × 100/4 = 19000 Now, we have to find simple interest on this sum at 10% rate in 5 years. SI = (P × r × t)/100 SI = (19000 × 10 × 5)/100 SI = 9500Related questions
