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 production of scooters in all factories equal to the yearly average number of scooters produced from 1985 to 1989?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 1985.

We know that,

Average = Sum of observations/Number of observations

Now,

Average number of scooters produced per year (in thousands) = Total production/5

⇒ (115 + 108 + 149 + 102 + 101)/5

⇒ 575/5 = 115

Hence,

The year in which the production of scooters in all factories equal to the yearly average number of scooters produced from 1985 to 1989 = 1985
