# What is the compound interest earned at the end of 3 years?I. Simple interest earned on that amount at the same rate and for the same period is Rs. 4500.II.The rate of interest is 10 p.c.p.a.III.Compound interest for 3 years is more than the simple interest for that period by Rs.465.

 A) I and II only B) II and III only C) I and III only D) Either II or III only

Answer:   D) Either II or III only

Explanation:

I. gives, S.I for 3 years = Rs. 4500.

II. gives, Rate = 10% p.a.

III. gives, (C.I.) - (S.I.) = Rs. 465.

Clearly, using I and III we get C.I. = Rs. (465 + 4500).

Thus, II is redundant.

Also, from I and II, we get sum =

100 x 4500

= 15000.

10 x 3

Now C.I. on Rs. 15000 at 10% p.a. for 3 years may be obtained.

Thus, III is redundant.

Either II or III is redundant.
