Correct Answer - Option 2 : Rs. 690
Given:
Profit with selling article to Rs. 536 = loss with selling an article to Rs. 384
Formula:
Profit = SP - CP
Loss = CP - SP
% Profit = [(SP - CP)/CP] × 100
Calculation:
Let CP be x, then
⇒ 536 − x = x - 384
⇒ 2x = 536 + 384
⇒ 2x = 920
⇒ x = 920/2 = Rs. 460
⇒ S.P of Article = 460 × (150/100) = Rs. 690
∴ The Selling price of charger at 50% profit is Rs. 690
