Q 6 - The genuine rebate on Rs 5125 due 6 months subsequently is Rs 125. The rate of interest per annum is:
Answer : A
Explanation
P.W. = Rs (5125-125) = Rs 5000 S.I. on Rs 5000 for 1/2 year is Rs 125 ∴ R = (100*125)/(5000*1/2)% p.a. = 5% p.a.
Q 7 - The straightforward hobby and the genuine rebate on a sure total due 6 months subsequently are Rs 25 and Rs 24 individually. The rate of interest per annum is:
Answer : D

((S.I.)*(T.D.))/((S.I.)-(T.D.))=Rs ((25*24))/((25-24))= Rs 600 S.I. on Rs 600 for 6 months is Rs 25 ∴ Rate = (100*125)/(600*6/12)% p.a. = 25/3% p.a.
