A and B together borrowed a sum of ₹51,750 at an interest rate of 7%p.a. compound interest in such a way that to settle the loan, A paid as much amount after three years as paid by B after 4 years from the day of borrowing. The sum (in ₹) borrowed by B was:

25,000

7% = \(\frac{7 }{100}\)

So,

Sum borrowed by B    :   Sum borrowed by A 

                  100          :      107

ATQ,

( 100 + 207 )R = 51750

207R = 51750

1R = 250

Now, Sum borrowed by B = 100R = 100 × 250 = Rs. 25000
