-
- ₹78.75
- ₹77.75
- ₹82.75
- ₹76.75
- None of these
Correct Option: A
We know that , True Discount = √P.W. × B.G.
75 = √1500 × B.G.
On Squaring both the sides,
75 × 75 = 1500 × B.G.
| Banker 's Gain = ₹ | 75 × 75 | = ₹ | 15 | ₹ = 3.75 |
| 1500 | 4 |
Banker 's Discount = True Discount + Banker 's Gain = 75 + ₹3.75 = ₹78.75.
