Correct Answer - Option 2 : Rs. 550
Given:
Selling price = Rs. 450,
loss % = 10%
Profit % = 10%
Formula used:
S.P. = C.P. × (100 – L%)/100
S.P. = C.P. × (100 + P%)/100
Where
S.P. → Selling price
CP → Cost price
L% → Loss %
P% ⇒ Profit %
Calculations:
S.P. = C.P. × (100 – L%)/100
So, CP = (SP × 100)/(100 – L%)
The cost price = (450 × 100)/(100 –10) = 450 × (100/90)
⇒ CP = 500
For 10% profit
S.P. = C.P. × (100 + P%)/100
⇒ S.P. = 500 × (100 + 10)/100 = Rs. 550
∴ The required selling price of the product is Rs. 550.
