Study carefully the table given below and answer the questions asked here under. In this table, the number (in thousands) of five types of products (A, B, C, D, E) manufactured against their respective year of manufacturing is given.
| Year | A | B | C | D | E |
|---|---|---|---|---|---|
| 2021 | 29 | 45 | 26 | 15 | 32 |
| 2022 | 32 | 52 | 58 | 26 | 35 |
| 2023 | 28 | 54 | 92 | 24 | 39 |
| 2024 | 26 | 58 | 86 | 27 | 34 |
| 2025 | 23 | 63 | 82 | 28 | 34 |
During which of the following years, manufacturing of product A was approximately equal to the average production of that year?
A2021 ✓ Correct
B2022
C2023
D2024
Correct answer: (A) 2021
Explanation
Find the yearly average, which is the sum of all five products divided by 5, and compare it with product A. For 2021 the total is 29+45+26+15+32 = 147, so the average is 147/5 = 29.4 thousand. Product A in 2021 is 29 thousand, almost exactly the average. The other years give averages of about 40.6, 47.4 and 46.2, far above their A values, so 2021 is the match.
