Answer:
the percentage profit of the company is 63.9%.
Explanation:
Cost of making pins= £1.10
Number of pins= 1000
Total cost for making the pins
= Cost of each pin × Number of pins
= £1.10 × 1000
= £1110
Percentage of pins sold in charities
= 35% of 1000 pins
= (35/100) × 1000
= 350 pins
Left pins= 1000-350 = 650 pins
Number of pins sold at £3.00:
= 60% of 650
= (60/100) × 650
= 390
Selling price of these 390 pins
= 390 × £3.00
= £1170
Number of pins sold at £5.00 for 2:
= 40% of 650
= (40/100) × 650
= 260
These 260 pins were sold in pairs for £5.
Therefore, number of pairs sold
= 260/2
= 130 pairs
Selling price of these 130 pairs of pins
= 130 × £5.00
= £650
Therefore, total selling price
= £1170 + £650
= £1820
Profit by company
= Selling price - Cost price
= £1820 - £1110
= £710
Profit percentage
= Profit × 100 / Total cost price
= 710 × 100 / 1110
= 71000/1110
= 63.9%
