Answer: 18.6%
Explanation:
Cost of 20 kg of beans at #150 per kg is:
= 20 * 150
= #3,000
Cost of 15 kg of beans at #180 per kg is:
= 15 * 180
= #2,700
Total cost is:
= 3,000 + 2,700
= #5,700
Mixing both beans results in a weight of:
= 20 + 15
= 35 kg
This 35kg is sold at #200 per kg so the revenue is:
= 35 * 200
= #7,000
Percentage profit is:
= (Revenue - Cost) / Revenue * 100%
= (7,000 - 5,700) / 7,000 * 100%
= 18.6%
