MAT Exam 2021 Paper

Concept:Profit is the excess of selling price over the total cost, which includes material, labour, and weekly overheads.Explanation:Let the number of units produced and sold per week be $x$.Selling price of $x$ units $= 60x$.Cost of materials and labour for $x$ units $= 40x$.Overhead expenses per week $= 3000$.Total cost per week $= 40x + 3000$.Profit $= 60x - (40x + 3000) = 20x - 3000$.He needs profit of at least ₹1000, so:$20x - 3000 \geq 1000$$20x \geq 4000$$x \geq 200$Thus, he must produce and sell a minimum of 200 units per week.Answer:200 units (Option D).
