Rs. 432
Rs. 540
Rs. 1080
Explanation:

 Sum = B.D. x T.D. = Rs. 72 x 60 = Rs. 72 x 60 = Rs. 360. B.D. - T.D. 72 - 60 12

7.
The certain worth of a certain sum due sometime hence is Rs. 1600 and the true discount is Rs. 160. The banker's gain is:
Rs. 20
Rs. 24

discount. The rate percent is:

 5 1 % 5
 9 1 % 11
 8 1 % 8
 6 1 % 6

 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
