Q:

A) I only | B) III only |

C) I or II only | D) .II and Either I or III only |

Answer: D) .II and Either I or III only

Explanation:

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 x 1200

= 5% p.a.

2 x 12000

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

Thus, I is redundant.

Hence, I or III redundant.
