Basha borrowed ₹ 8,500 from a bank at a particular rate of simple interest. After 3 years, he paid ₹ 11,050 to settle his debt. At what rate of interest he borrowed the money?

योग

उत्तर

Let the rate of interest be r% per annum

Here Principal P = ₹ 8,500

Time n = 3 years

Total amount paid = ₹ 11,050

A = P + 1 = ₹ 11,050

i.e. 8,500 + 1 = ₹ 11,050

I = ₹ 11,050 – ₹ 8,500 = ₹ 2,550

Also we know that I = `"Pnr"/100` = ₹ 2,550

`(8,500 xx 3 xx "r")/100` = ₹ 2,550

r = `(2550 xx 100)/(8500 xx 3)`

r = 10%

Rate of interest r = 10%
