Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 30.1
The total exports of computers, by the company, in 2013,2014 and 2018 = 140 + 240 + 270 = 650
The total production of computers in 2015 to 2017 = 300 + 340 + 290 = 930.
Required % = (930 - 650)/930 × 100 = 30.1%
