Study carefully the table given below and answer the question asked here under. In this table, number (in thousands) of five types of products (i.e. A, B, C, D, E) manufactured against their respective year of manufacturing are given.
Year | A (in thousands) | B (in thousands) | C (in thousands) | D (in thousands) | E (in thousands) |
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 |

2024
Attempted by 17 students.
Show answer & explanation
Correct answer: A
To determine the year when the manufacturing of product A was approximately equal to the average production across all products, calculate the average for each year and compare it with product A's production.
For 2021: (29 + 45 + 26 + 15 + 32) / 5 = 147 / 5 = 29.4 thousand units. Product A produced 29 thousand, which is very close to the average.
For 2022: (32 + 52 + 58 + 26 + 35) / 5 = 203 / 5 = 40.6 thousand units. Product A produced 32, which is not close.
For 2023: (28 + 54 + 92 + 24 + 39) / 5 = 237 / 5 = 47.4 thousand units. Product A produced 28, which is not close.
For 2024: (26 + 58 + 86 + 27 + 34) / 5 = 231 / 5 = 46.2 thousand units. Product A produced 26, which is not close.
For 2025: (23 + 63 + 82 + 28 + 34) / 5 = 230 / 5 = 46 thousand units. Product A produced 23, which is not close.
Only in 2021 is the production of product A (29 thousand) approximately equal to the average (29.4 thousand).
Therefore, the correct year is 2021.
