Study the given table and answer the question that follows.
The table shows the yearly production (in thousands) of scooters in five different factories (P, Q, R, S, and T) from 1985 to 1989.
Yearly production (in thousands) of scooters in different factories.
| Factory | 1985 | 1986 | 1987 | 1988 | 1989 |
| P | 20 | 15 | 24 | 13 | 17 |
| Q | 16 | 23 | 41 | 20 | 15 |
| R | 14 | 21 | 30 | 16 | 12 |
| S | 25 | 17 | 15 | 12 | 22 |
| T | 40 | 32 | 39 | 41 | 35 |
| Total | 115 | 108 | 149 | 102 | 101 |
In which year was the total production of scooters of all factories 20% of the total production of scooters from 1985 to 1989?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1985.
The total production of scooters from 1985 to 1989 = 115 + 108 +149 + 102 + 101 = 575.
20% of the total production of scooters from 1985 to 1989 = 20% of 575 = 115.
Hence, in 1985 the total production of scooters of all factories was 20% of the total production of scooters from 1985 to 1989.
