If the selling price of an article is Rs. 540 and the profit is 35%, find the cost price. MCQ with Answer and Explanation

Explanation:
Difference in percentage = 12% - (-16%) = 28%. 28% of Cost Price = 42. Cost Price = (42 / 28) * 100 = 150.

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:
Let CP = 100, MP = 145, SP = 145*0.8 = 116, profit = 16%.
