If the sales of Product C increase by 50% and the sales

Solution

First, calculate the sales for each product based on the given percentages. Sales for Product A = 40% of ₹1,200,000 = (40 / 100) × ₹1,200,000 = ₹480,000. Sales for Product B = 30% of ₹1,200,000 = (30 / 100) × ₹1,200,000 = ₹360,000. Sales for Product C = 20% of ₹1,200,000 = (20 / 100) × ₹1,200,000 = ₹240,000. Sales for Product D = 10% of ₹1,200,000 = (10 / 100) × ₹1,200,000 = ₹120,000. Now, calculate the new sales amounts after the changes: New sales for Product C = ₹240,000 + (50% of ₹240,000) = ₹240,000 + ₹120,000 = ₹360,000. New sales for Product D = ₹120,000 - (20% of ₹120,000) = ₹120,000 - ₹24,000 = ₹96,000. Now, calculate the new total sales: New total sales = Sales of Product A + Sales of Product B + New sales of Product C + New sales of  Product D = ₹480,000 + ₹360,000 + ₹360,000 + ₹96,000 = ₹1,296,000. Correct Answer: d) ₹1,296,000
