Store wise details of air cooling devices
| Store | Total Number of Devices Sold | Ratio (AC : Cooler : Fan) | Selling Price AC (₹) | Cooler (₹) | Fan (₹) |
|---|---|---|---|---|---|
| A | 1250 | 4 : 5 : 1 | 14000 | 4000 | 750 |
| B | 450 | 3 : 2 : 4 | 15000 | 4500 | 800 |
| C | 850 | 6 : 4 : 7 | 16000 | 5000 | 850 |
| D | 900 | 4 : 2 : 3 | 17000 | 5500 | 900 |
| E | 1000 | 5 : 1 : 4 | 18000 | 6000 | 950 |
| F | 605 | 2 : 4 : 5 | 19000 | 6500 | 1000 |
Income that came from the sale of Coolers by Store D was _________ % more than the income that came from the sale of Fans by Store F.
Store D sells 200 Coolers at 5500 rupees each, so its Cooler income is 11 lakh. Store F sells 275 Fans at 1000 rupees each, so its Fan income is 2 lakh 75 thousand. The difference between them is 8 lakh 25 thousand, and that difference is exactly three times Store F's Fan income, so it is 300 percent more. That is why the answer is 300.
