A person purchased 12 bags of sugar at the rate of Rs. 1200 per bag, 8 bags at the rate of Rs. 1500 per bag and 10 bags at the rate of Rs. 2100 per bags. What will be the average cost of all the bags together?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Rs. 1580
Average = Sum/Total number
A person purchased 12 bags of sugar at the rate of Rs. 1200 per bag
Sum of 12 bags = 12 × 1200 = 14400
Sum of 8 bags = 8 × 1500 = 12000
Sum of 10 bags = 10 × 2100 = 21000
Average = Total Sum/Total number
Average = (14400 + 12000 + 21000)/(12 + 8 + 10)
Average = 47400/30
Average = 1580
