Correct Answer - Option 2 : Rs. 5390
Given∶
Selling price = Rs. 4312
Loss = 12%
Formula used∶
CP = SP × 100/(100 – L%)
SP = CP × (100 + P%)/100
CP → Cost price, SP → Selling price, P → Profit and L → Loss
Calculation∶
CP = 4312 × 100/(100 – 12)
⇒ CP = 4900
New SP will be 4900 × (100 + 10)/100.
⇒ New SP = 4900 × 11/10
⇒ New SP = 5390
∴ He should sell an article at Rs. 5390 to gain 10%
