Detailed Solution
Download Solution PDFGiven:-
The selling price of 9 boxes is equal to the cost price of 15 boxes
Formula used:-
Profit (P) = Selling Price (SP) - Cost price (CP)
Profit% = ( Profit /CP) × 100
Calculation:-
Let the cost price of 1 box = Rs.1
So, the cost price of 9 boxes = Rs.9
As per the question,
The Selling price of 9 boxes = cost price of 15 boxes
Gain = SP - CP
⇒ 15 - 9 = 6
Gain percent (%) = (6/9) × 100 = 200/3 %
∴ The required answer is 200/3 %.
Alternate MethodGiven,
15 × CP = 9 × SP
⇒ SP/CP = 15/9
⇒ SP/CP = 5/3
⇒ Profit % = [(5 - 3)/3] × 100
⇒ Profit % = 200/3%
