Question

A florist bought 360 roses at 120 rupees per dozen.If he sold them at 12 rupees each , what is his profit as a percentage of his cost price?​

Answer 1

Cost of 1 dozen roses = 120 rs

cost of 1 rose = 10 rs

CP of all roses = 360×10 = 3600

SP of all roses = 360×12 = 4320

profit = SP - CP = 4320-3600 = 720

Profit% = (profit/CP × 100) %= (720/3600 ×100) % = 20%
