Best answer
Correct Answer - Option 4 : A in 2019

Given:

State/Year A B C D E
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

Formula used:

Average = Sum of observation/Total number of observation

Calculation:

First, find the average of E

⇒ (117 + 120 + 132 + 133 + 145 + 187)/6

⇒ 834/6 = 139

Now, find 1.1 times of 139

⇒ 139 × 1.1 = 152.9

Which is closed to A in 2019 - 153

∴ A in 2019 is the closest to 1.1 times the average of E in 6 years.
