- Start by calculating the effective discount for both cases.

- A single discount of 35% means you pay 65% of the bill.

- Two successive discounts of 20% and 20% means:

- Pay 80% of the first discount.

- Then, on the reduced amount, pay 80% again.

- Resulting in an effective discount of 36% (0.8 * 0.8 = 0.64, so pay 64%).

- The difference between a 35% discount and a 36% discount is 1% of the bill.

- Given this difference amounts to Rs 22, calculating it gives:

- 1% of the bill = Rs 22.

- Therefore, 100% (or the full amount) of the bill is Rs 2,200.

- Correct option: Rs 2,200
