SSC GD 2021 PYQ — Question 67

The correct answer is option 3 i.e. Gain, 12$\frac{1}{2}$

Given:

Selling price = 91

Profit% = 30%

Formula used:

Selling price = Cost price(1 + Profit%)         ---- (1)

Profit = Selling price - Cost price             ---- (2)

Profit% = (Profit/Cost price) × 100            ---- (3)

Calculations:

Using equation (1), we get

Cost price = 91/1.3 = 70

Using equation (2),

Profit = 78.75 - 70 = 8.75

Using equation (3), we get

Profit% = (8.75/70) × 100 = 12.5%
