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

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.

A) 44 B) 22
C) 24 D) 11

2X = 44

X = 22.

 

Therefore, cost of each literature text book = Rs. X = Rs. 22.

And that of masthematics = X + 2 = Rs. 24.
