Direction : Study the following table and answer the questions that follow : Number of sanitizers sold by companies A, B, C and D in 2021 and 2022Year →
Company ↓Number of Sanitizers Sold 2021 2022 A 230 240 B 350 380 C 310 390 D 270 310
The combined number of sanitizers sold by Companies B and C in 2022 is what percentage of their (Companies B and C) combined sales in 2021 (Round off to two decimal places) ?
116·67%
“X is what percentage of Y” means \(\dfrac{X}{Y} \times 100\), with X the 2022 combined sales and Y the 2021 combined sales of Companies B and C.
Step 1 — 2022: \(380 + 390 = 770\).
Step 2 — 2021: \(350 + 310 = 660\).
Step 3 — Percentage = \(\dfrac{770}{660} \times 100 = \dfrac{7}{6} \times 100 = 116.666\ldots \approx 116.67\%\).
120·56%, 112·53% and 125·86% do not equal 770 over 660 as a percentage, so they are wrong.
116·67% option is correct.
