Question

Ravi borrowed a sum of money for 3 years at the rate of 10% per annum compounded annually. gaurav borrowed the same amount of money for the same time and at the same rate but at simple interest. the difference between the interest by Ravi and gaurav is rupees 1488, find the sum borrowed by them​

Answer 1

Here the principal is unknown .

Let the principal be p

Amount for ci = p(1 +10/100)3

= 1331p/1000

Amount =1331p/1000

Then

Ci = amount -principal

= 1331p/1000 - p

= 331p/1000

Ci =331p/1000

Now

Si = (p× 10×3)/100

= 3p/10

A/q

CI -SI =1488

331p/1000 -3p/10 =1488

31p/1000 = 1488

31p = 1488000

P= 48000

So the principal is 48000
