The banker's gain on a certain sum due 1 1 years hence is 3 of the banker's 2 25 discount. The rate percent is:

Correct Answer: 9 1 % 11

Explanation:

Let, B.D = Re. 1.



Then, B.G. = Re. 3 .
25



∴ T.D. = (B.D. - B.G.) = Re. 1 - 3 = Re. 22 .
25 25



Sum = 1 x (22/25) = Rs. 22 .
1-(22/25) 3



S.I. on Rs. 22 for 1 1 years is Re. 1.
3 2



∴ Rate = 100 x 1 ❩%
= 100 = 9 1 %.
11 11
22 x 3
3 2
