| State→ | A | B | C | D | E |
| Year ↓ | |||||
| 2014 | 112 | 130 | 136 | 105 | 117 |
| 2015 | 122 | 138 | 150 | 140 | 120 |
| 2016 | 124 | 134 | 142 | 144 | 132 |
| 2017 | 132 | 154 | 198 | 149 | 133 |
| 2018 | 135 | 148 | 187 | 151 | 145 |
| 2019 | 153 | 136 | 198 | 150 | 187 |
By what percentage is the total consumption of coffee in state D from 2014 to 2016 less than the total consumption of coffee in the states A, B, C and E in 2015(correct to one decimal place)?
Answer & explanation
Correct answer: option 1
Total consumption of coffee in state D from 2014 to 2016 = 105 + 140 + 144
= 389
Total consumption of coffee in the states A, B, C and E in 2015 = 122 + 138+ 150 + 120 = 530
Required percentage = \(\frac{530 - 389 }{530}\) × 100
= \(\frac{ 141 }{530}\) × 100
= 26.7%
