Given:

Successive discounts are 30% and 20%

He sold it at Rs. 112 after two discounts

Concept used:

If two successive discounts are x% and y%, then total discount percentage is given by [x + y – xy/100]%

Calculation:

Total discount percentage = 30 + 20 – (30 × 20)/100

⇒ Total discount = 50 – 6 = 44%

Marked price × 56/100 = 112

Marked price = 112 × (100/56) = 200

∴ Marked price is Rs. 200

Let the marked price be Rs. x

After 30% discount,

Selling price = x – 0.30x = 0.70x

After allowing another successive discount of 20%,

∴ Selling price = 0.70x – [(0.70x) × 0.20] = 0.70x - 0.14x = 0.56x

According to the question,

⇒ 0.56x = 112

x = 112/0.56 = Rs. 200

∴ Marked price is Rs. 200
