Bihar Police Constable Model Paper 6

Given :-
A shop keeper buys an article for Rs. 440 and his overhead expenses are Rs. 60
Selling price of article = Rs. 550
Concept :-
Total cost price = original cost price + overhead expenses
Profit = Selling price - Cost price
Profit % = (Profit/CP) × 100
Calculation :-
⇒ Total cost price = 440 + 60
⇒ Total cost price = 500
⇒ Profit = 550 - 500
⇒ Profit = Rs. 50
⇒ Profit % = (50/500) × 100
⇒ Profit % = 10%
∴ Profit % = 10%
