Question : In a megastore, the following data reveals the units purchased during the years. What is the percentage growth in total units purchased (of all three products) from 2015 to 2020?
| Year | Tea | Coffee | Cold drink |
| 2015 | 650 | 450 | 1008 |
| 2016 | 730 | 402 | 1092 |
| 2017 | 710 | 354 | 770 |
| 2018 | 570 | 438 | 812 |
| 2019 | 820 | 390 | 1043 |
| 2020 | 830 | 501 | 1330 |
Option 1: 21.68 percent
Option 2: 22.75 percent
Option 3: 26.23 percent
Option 4: 25.76 percent
Correct Answer: 26.23 percent
Solution :
Total units purchased in 2015:
Tea = 650
Coffee = 450
Cold drink = 1008
Total = 650 + 450 + 1008 = 2108 units
Total units purchased in 2020:
Tea = 830
Coffee = 501
Cold drink = 1330
Total = 830 + 501 + 1330 = 2661 units
Now, let's find the percentage increase:
Percentage increase = $(\frac{(\text{Total units in 2020} - \text{Total units in 2015})}{\text{Total units in 2015}}) × 100$
= $(\frac{(2661 - 2108)}{2108}) \times 100$
= $(\frac{553}{2108}) \times 100$
= $0.2623 \times 100$
= $26.23\%$
So, the percentage growth in total units purchased from 2015 to 2020 is approximately 26.23%.
Hence, the correct answer is 26.23%.
