SSC Selection Post 2020 PYQ — Question 62

The correct answer is option 4 i.e. Gain : 2.8%.

Selling Price 1 (SP₁) = ₹265.50

Gain % on SP₁ = 18%

SP = CP × ( 1 + Gain % / 100)

$265.50 = \text{CP} \times \left(1 + \frac{18}{100} \right) = \text{CP} \times 1.18$

CP  = $\frac{265.50}{1.18} = 225$

Selling Price 2 (SP₂) = ₹231.30

The gain/loss % on this selling price compared to CP = ₹225

Profit or Loss = SP  -  CP = 231.30 - 225 = 6.30 ⇒ Gain

Gain % =$\frac{6.30}{225} \times 100 = 2.8\%$
