Total cost for A = ₹600 × 3,000 = ₹18,00,000. Total cost for B = ₹800 × 2,000 = ₹16,00,000. Total cost = ₹18,00,000 + ₹16,00,000 = ₹34,00,000. Selling price of 80% at 25% profit: 80% of production = (80/100) × 5,000 = 4,000 units. Cost of 4,000 units = ₹34,00,000 × (4,000 / 5,000) = ₹27,20,000. Selling price = ₹27,20,000 × 1.25 = ₹34,00,000. Selling price of 20% at 10% loss: 20% of production = 1,000 units. Cost of 1,000 units = ₹34,00,000 × (1,000 / 5,000) = ₹6,80,000. Selling price = ₹6,80,000 × 0.90 = ₹6,12,000. Total selling price = ₹34,00,000 + ₹6,12,000 = ₹40,12,000. Profit = ₹40,12,000 - ₹34,00,000 = ₹6,12,000. Profit percentage = (₹6,12,000 / ₹34,00,000) × 100 = 18%. Correct option: b
[(5/6 of 719.81) + 30% of 499.79] × (√99.89 + 25% of 399.69) = ?
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04
14.232 + 19.98% of 629.99 = ? × 6.99
447.79 ÷ √(√2400) + 30.94 × 6.07 – 5.08 × 21.96 = ?
{(440.89 ÷ 20.74) ÷ 2.88} × 48.65 = ? 3
32.12% of 2399.98 + 64.04% of 2499.95 = ? × 15.95
4821.49 - 3123.87 + 5643.92 + ? = 11500.68
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
