Solution:
1).
Average scooters produced during 1985 – 89
=
(115 + 108 + 149 + 102 + 101) / 5 = 575 / 5 = 115
Average scooters produced during 1985 – 89 is
equal to the total production of scooters in 1985
Answer: a)
2).
Decrease in production in 1989 from 1988 of factory
Q = [(20 – 15) / 20 ] × 100 = 25%
R = [(16 – 12) / 16 ] × 100 = 25%
T = [(41 – 35) / 41 ] × 100 – 14.6%
Required answer is factory Q and R
Answer: c)
3). Required ratio =
20 : 40 = 1 : 2
Answer: b)
4).
In 1987 total production of scooters was maximum
Answer: c)
5).
Total production of scooters during 1985 – 89 = 575
Total production of scooters of all factories
as a percent of total production of scooters during 1985 – 89 in
1985 = (115 / 575) × 100 = 20%
1986 = (108 / 575) × 100 = 18.78%
1987 = (149 / 575) × 100 = 25.91%
1988 = (102 / 575) × 100 = 17.74%
1989 = (101 / 575) × 100 = 17.56%
