- A97.5
- B101.5
- C98
- D100
Solution & Step-by-step Explanation
To find the average price per kg, we use the weighted average formula:
Average Price=
Total weight of fruits
(Weight of apples×Price of apples)+(Weight of grapes×Price of grapes)
Given data:
Weight of apples =10kg, Price =₹94.50/kg
Weight of grapes =5kg, Price =₹105/kg
Total amount received=(10×94.50)+(5×105)
Total amount received=945+525=1470
Total weight=10+5=15kg
Average amount per kg=
15
1470
=98
Average Price=
Total weight of fruits
(Weight of apples×Price of apples)+(Weight of grapes×Price of grapes)
Given data:
Weight of apples =10kg, Price =₹94.50/kg
Weight of grapes =5kg, Price =₹105/kg
Total amount received=(10×94.50)+(5×105)
Total amount received=945+525=1470
Total weight=10+5=15kg
Average amount per kg=
15
1470
=98
