Correct Answer - Option 2 : approximately 42%
Given:
Discount 1 percent = 22%
Discount 2 percent = 17%
Discount 3 percent = 11%
Calculation:
Let the initial price be 100
Discount 1 = 22% of 100
Discount 1 = 22
Price after discount 1 = 100 – 22 = 78
Discount 2 = 17% of 78
Discount 2 = 13.26
Price after discount 2 = 78 – 13.26 = 64.74
Discount 3 = 11% of 64.74
Discount 3 = 7.1214
Price after discount 3 = 64.74 – 7.1214
Final price after third discount = 57.6186
Total discount = Initial price – Final price = 100 – 57.6186 = 42.3814
Total discount ≈ 42
Discount% ≈ (Total discount/Initial price) × 100
⇒ Discount% ≈ (42/100) × 100
⇒ 42%
∴ Discount percentage is approximately 42%
