Question : The table below shows the number of the AC that were sold by the showroom in the years 2013 to 2016. How much percentage of AC sold by Showroom B in 2014 is less than that of Showroom D in 2016?
| Showroom | Years | |||
| 2013 | 2014 | 2015 | 2016 | |
| A | 100 | 54 | 98 | 72 |
| B | 180 | 92 | 105 | 88 |
| C | 120 | 122 | 100 | 140 |
| D | 60 | 152 | 80 | 100 |
Option 1: 10%
Option 2: 14%
Option 3: 8%
Option 4: 12%
Correct Answer: 8%
Solution :
AC sold by D in 2016 = 100
AC sold by B in 2014 = 92
Difference = 100 – 92 = 8
$\therefore$ Required percentage = $\frac{\text{Difference}}{\text{Sales of D in 2016}}\times100=\frac{8}{100}\times100= 8\%$
Hence, the correct answer is 8%.
