Given:

Selling Price (SP) = ₹1,700

Loss = 15%

Gain = 20%

Formula used:

Cost Price (CP) = \(\dfrac{SP}{1 - \frac{Loss \%}{100}}\)

New Selling Price (SPnew) = \((1 + \frac{Gain \%}{100}) \times CP\)

Calculations:

CP = \(\dfrac{1700}{1 - \frac{15}{100}}\)

⇒ CP = \(\dfrac{1700}{0.85}\)

⇒ CP = ₹2,000

SPnew = \((1 + \frac{20}{100}) \times 2000\)

⇒ SPnew = \(1.20 \times 2000\)

⇒ SPnew = ₹2,400

∴ The correct answer is  ₹2,400
