Option 1 : 2%

**Given:**

Discount percent = 15%

Marked percent = 20% above cost price

**Concept used:**

When there is a gain of x% and a loss of y% the net effect is given by [x - y - (xy/100)]% profit or loss according to positive or negative sign, respectively.

**Calculation:**

Here, x = 20% and y = 15%

According to the question

Net effect = [20 - 15 - {(20 × 15)/100}]%

⇒ (5 - 3)%

⇒ 2%

**∴ The gain percent is 2%.**

The positive sign shows profit and the negative sign shows loss.

__Alternate Method__

Let the Cost Price (CP) be 100

Marked price = CP + 20% of CP

⇒ Marked price = 100 + 20 = 120

Selling price (SP) = Marked price - Discount

⇒ SP = 120 - 15% of 120 = 120 - 18

⇒ SP = 102

Gain = SP - CP = 102 - 100 = 2

Gain% = (Gain/CP) × 100

⇒ Gain% = (2/100) × 100 = 2%

∴ The gain percent is 2%.
