Q:

Gopal borrowed some money at 12% simple interest. If he had to pay back Rs. 1280 after 5 years, in order to clear off the loan. How much did he borrow?

A) Rs. 800 B) Rs. 620
C) Rs. 560 D) Rs. 480
 
Answer & Explanation Answer: A) Rs. 800

Explanation:

Let the principle amount be Rs. P

Interest rate = 12%

Total amount he paid after 5 years = Rs. 1280

ATQ, 

P + I = PTR100 + P1280 = PTR100 + 11280 = P5 x 12100 + 116P10 = 1280P = 80 x 10 = 800

 

Hence, the amount he borrowed = P = Rs. 800.
