PSLE A company offered 200 food processors at 30% discount during a 7-day sale. The line graph shows the number of food processors left unsold at the end of each day.
- On which day was the most number of food processors sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 200 food processors were sold in the first five days of the sale?
- During the sale, the discounted price of the food processors was $98. After the sale, the remaining food processors were sold without discount. What was the total amount of money collected from selling all 200 food processors?
(a)
The steepest line is from Day 1 to Day 2.
On Day
2, the most number of food processors was sold.
(b)
Number of food processors that were left at Day
5 = 80 Number of food processors that were sold for the first five days = 200 - 80 = 120 Percentage of food processors that were sold for the first five days
=
120200 x 100%
= 60%
(c)
Number of food processors that were left at the end of the sale = 30
Number of food processors that were sold during the sale
= 200 - 30
= 170
Total amount that collected from the food processors sold
= 170 x 98
= $16660
Price of each food processor after 30% discount
= 100% - 30%
= 70%
70% of the price = 98
1% of the price = 98 ÷ 70 = 1.4
100% of the price = 100 x 1.4 = 140
Amount collected from selling the remaining food processors
= 30 x 140
= $4200
Total amount collected from selling all the 200 food processors
= 16660 + 4200
= $20860
Answer(s): (a) Day
2; (b) 60%; (c) $20860
