Question

Riya bought ₹ 15,000 from a bank to buy a car at 10% simple interest. If she paid ₹ 9,000 as interest while clearing the loan, find the time for which the loan was given

Sum

Solution

Here Principal (P) = ₹ 15,000

Rate of interest (r) = 10%

Simple Interest (I) = ₹ 9000

I = Pnr100

9000 = 15000×n×10100

n = 9000×10015000×10

n = 6 years

∴ The loan was given for 6 years
