  1. 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?
    1. Rs. 180
    2. Rs. 120
    3. Rs. 220
    4. 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 .
