1.A bank offers 5% compound interest calculated on half-yearly basis. A customer deposits Rs. 1600 each on 1stJanuary and 1stJuly of a year. At the end of the year, the amount he would have gained by way of interest is:

A.Rs. 120B.Rs. 121

C.Rs. 122D.Rs. 123

Answer & ExplanationAnswer:OptionBExplanation:Amount= Rs.1600 x1 +52+ 1600 x1 +5

2 x 1002 x 100

= Rs.1600 x41x41+ 1600 x41

III.The amount borrowed is 10 times the simple interest in 2 years.

A.I only

B.III only

C.I or II only

D.II and Either I or III only

E.All I, II and III are required

Answer & ExplanationAnswer:OptionDExplanation: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.

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

E.Any two of the three

Answer & ExplanationAnswer:OptionDExplanation: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.View AnswerWorkspaceReportDiscuss in Forum
