Mr. Gupta borrowed a sum of money on compound interest. What will be the amount to be repaid if he is repaying the entire amount at the end of 2 years? I. The rate of interest is 5 p.c.p.a. II. Simple interest fetched on the same amount in one year is Rs. 600. III. The amount borrowed is 10 times the simple interest in 2 years.

Correct Answer: II and Either I or III only

Explanation:

   I. gives, Rate = 5% p.a.


 


 II. gives, S.I. for 1 year = Rs. 600.


 


III. gives, sum = 10 x (S.I. for 2 years).


 



 Now I, and II give the sum.


 For this sum, C.I. and hence amount can be obtained.


 Thus, III is redundant.


 Again, II gives S.I. for 2 years = Rs. (600 x 2) = Rs. 1200.


 Now, from III, Sum = Rs. (10 x 1200) = Rs . 12000.


Thus,Rate = 100 * 1200 2 * 12000  =5%


Thus, C.I. for 2 years and therefore, amount can be obtained.


Thus, I is redundant.


Hence, I or III redundan
