Solution :
Amount = INR 7500
1. Two successive discounts of 5% and 5%
Net discount % = $5 +5- \frac{5×5}{100}$ = $9.75$
2. Single discount of 10%
3. Two successive discounts of 8% and 2%
Net discount % = $8 +2- \frac{8×2}{100}$ = $9.84$
So, the maximum discount is from option 2, which is a single discount of 10%.
Hence, the correct answer is 2.
