8. The banker's discount on a certain sum due 2 years hence is 11 / 10 of the true discount.The rate percent is
A. 11% B. 10%
C. 5% D. 5.5%
Answer:
Let T.D be Rs 1.Then, B.D =Rs.11 / 10
= Rs.1.10.
Sum =Rs.(1.10 x 1/ 1.10-1)
= Rs.(110 / 10)
= Rs=11.
S.I on Rs.11 for 2 years is Rs.1.10.
Rate =(100 x 1.10 / 11 x 2)%
= 5%
