Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 5%.
Total Cost of 20 kg sugar at Rs 45 per kg = 20 × 45 = Rs 900.
Total cost of 25 kg of sugar at Rs 50 per kg = 25 × 50 = Rs 1250.
Total cost of 35kg of sugar at Rs 40 per kg = 35 × 40 = Rs 1400.
Total cost = 3550 + 450 = Rs 4000.
The total selling price of the whole sugar = 80 × 52.5 = Rs 4200.
Profit % = 200/4000 × 100 = 5%
