Best answer
Correct Answer - Option 3 : 20%

GIVEN:

Marked Price = Rs.150 & Selling Price = Rs.105 and 2nd Discount = 12.5%

FORMULA USED:

MP × (100 - Discount %)/100 = SP

CALCULATION:

Let 1st Discount be x%

⇒ MP × (100 - Discount %)/100 = SP

⇒ 150 × (100 - x)% × (100 - 12.5)% = 105

⇒ 150 × (100 - x)% × 87.5% = 105

⇒ (100 - x) = (105 × 10000)/87.5 × 150

⇒ 100 - x = 80

⇒ x = 20

∴ First Discount is 20%
