Question

sanju borrowed a sum of money from simran at 8% interest per annum. after 4 years, sanju had to give simran ₹9900 to clear the debt. what was the amount sanju borrowed originally?​

Answer 1

Step-by-step explanation:

Suppose Sanju had borrowed ₹ x from Simran.

Then,

Principal (P) = ₹ x

Rate (r) = 8% p.a.

Time (t) = 4 years.

Therefore, interest (SI)= Prt/100

=₹ x×8×4/100 = ₹ 32x/100

Amount =P+SI

=₹ (x+32x/100) =₹(132x/100)

This is the amount that had to be returned.

Therefore,

132x/100 =9900

=> x =7500

Therefore, sum that was borrowed = ₹x = ₹ 7500 [Answer]
