The banker’s discount of a certain sum of money is Rs. 36 and the true discount on the same sum for the same time is Rs. 30. What is the sum due?
-
- Rs. 180
- Rs. 120
- Rs. 220
- Rs. 200
Correct Option: A
Here , Banker's Discount = Rs 36 and True Discount = Rs 30
As we know that ,
∴ F = | Banker's Discount x True Discount | |
Banker's Discount - True Discount |
∴ F = | 36 x 30 | |
36 - 30 |
∴ F = | 36 x 30 | |
6 |
⇒ F = 36 x 5 = Rs.180
Thus , the sum due is Rs.180 .
