Given;
purchased,
- 3 dozen apples at Rs 240/dozen
- 2 dozen apples at Rs 360/dozen
- 5 dozen apples at Rs 180/dozen
To Find;
- Average cost of the Apple
Solution;
- Total cost of 3 dozen apples = 3 × 240
= Rs 720
- Total cost of 2 dozen apples = 2 × 360
= Rs 720
- Total cost of 5 dozen apples = 5 × 180
= Rs 900
- total number of apples purchased
= (3 × 12)+(2 × 12)+(5 × 12)
= 36 + 24 + 60
= 120
Therefore;
Total cost of all the apples = 720 + 720 + 900
= Rs 2340
Formula Used;
- Average cost of apples
= total cost / total number of apples
Substituting the values;
Average cost = 2340/120
= Rs 19.5
Conclusion;
- The average cost of the Apple is Rs 19.5
