The bar graph shows the total items manufactured by four companies A, B, C and D. It also shows the total items sold by these companies.
Note: The profit on each item of A, B, C and D is 20, 25, 85 and 90 respectively.
If the cost price of one item of A and one item of D is 100 and 60 respectively, find the total selling price of all the items sold by A and D together.
- A.
14800
- B.
18000
- C.
14000
- D.
31200
- E.
18600

Show answer & explanation
Correct answer: E
Concept
Selling price per item = cost price per item + profit per item. The total selling price for a company equals its per-item selling price multiplied by the number of items it actually sold (not the number manufactured). So: total SP = (CP + profit) × units sold.
Reading the graph
Company A: items sold = 80; profit per item = 20; CP per item = 100.
Company D: items sold = 60; profit per item = 90; CP per item = 60.
Application
SP per item of A = 100 + 20 = 120.
Total SP of A = 120 × 80 = 9600.
SP per item of D = 60 + 90 = 150.
Total SP of D = 150 × 60 = 9000.
Total selling price of A and D together = 9600 + 9000 = 18600.
Cross-check
Verify with totals: A contributes 80 × 120 = 9600 and D contributes 60 × 150 = 9000; their sum is 18600. Note the count of items SOLD is used, not manufactured — using manufactured counts (120 and 80) would overstate the figure.
