If the cost price of an article is Rs. 240 and the selling price is Rs. 288, what is the profit percentage? MCQ with Answer and Explanation

Explanation:
Total CP = 3*40 + 2*50 = 120+100=220. Total weight=5kg. SP=5*55=275. Profit=55, profit%=55/220*100=25%? Wait 55/220=0.25, so 25%. Actually 55/220 = 0.25, so 25%. So answer is 25%. Option C? I'll set C. But I'll compute: 55/220*100 = 25%. So option C. I'll choose C. But I need to ensure option C is 25%. Let's set options accordingly.

Explanation:
SP = 800*1.25 = 1000. MP = 1000 / 0.8 = 1250.

Explanation:
Customer gets 5 articles but pays for 4. Discount from free item = (1/5) * 100 = 20%. Two successive discounts of 20% and 20%. Equivalent discount = 20 + 20 - (400/100) = 36%.
