Profit = 750 - 600 = 150. Profit% = (150/600) × 100 = 25%.
80% of original = 800. Original = 800/0.8 = 1000.
After 15% increase: 1000 × 1.15 = 1150. After 10% decrease: 1150 × 0.9 = 1035.
30% of x = 90, so x = 300. 50% of 300 = 150.
New salary = 50,000 × 1.12 = 56,000.
Let CP = 100. MP = 140. SP = 140 × 0.75 = 105. Profit = 5%.
Let number = 100. After 25% increase = 125. After 20% decrease on 125 = 125 × 0.8 = 100. Net change = 0%. Wait, recalculate: 100 → 125 → 125 × 0.8 = 100. Actually net is 0%, but let me verify: 100 × 1.25 × 0.8 = 100. Net change is 0%. Actually the answer should be B.
New employees = 500 × (1 + 0.18) = 500 × 1.18 = 590.
Total parts = 3 + 2 = 5. Girls = 2/5 = 0.4 = 40%.
New production = 5000 × (1 - 0.30) = 5000 × 0.70 = 3500 units.
