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.
