Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 26.23 percent
Calculations:
Total units purchased (in 2015) = 650 + 450 + 1008 = 2108
Total units purchased (in 2020) = 830 + 501 + 1330 = 2661
Required percentage growth = [(2661 - 2108)/2108] × 100
⇒ [553/2108] × 100 = 26.23%
