Answer:
Option a is correct.
Step-by-step explanation:
Cost of 1 kg of rice = 5
Cost of 20 kg of rice = 20 × 5 = 100
Cost of 1 kg of another rice = 7
Cost of 35 kg of another rice = 35 × 7 = 245
Total kg of both rice = 35 + 20 = 55 kg
Total cost of 55 kg of two rices = 245 + 100 = 345
Cost of i kg of the mixed rice = 345/55 = 6.27
SP of the mixed rice = 6.50
Profit money per kg = 6.50 - 6.27 = 23 paise = 0.23
Profit money of 55 kg = 6.50 × 55 = 357.5 - 345 = 12.5
Profit % = 12.5/345 × 100
= 3.623%
Option a is correct.
