प्रश्न

In what time will ₹ 17800 amount to ₹ 19936 at 6% per annum?

बेरीज

उत्तर

Let the require time be n years

Here Principal P = ₹ 17,800

Rate of interest r = 6% per annum

Amount A = ₹ 19,936

A = P + I

19936 = 17800 + I

19936 – 17800 = I

2136 = I

Simple Interest (I) = `"Pnr"/100`

2136 = `(17800 xx "n" xx 6)/100`

n = `(2136 xx 100)/(17800 xx 6)`

n = `2136/(178 xx 6)`

n = 2 years

Required time = 2 years
