Production of cars by a company

-
The percent increase in total production of all types of cars in 1993 to that in 1991 was?
-
- 15
- 20
- 25
- 30
Correct Option: B
From above given table , we have
Total production in 1991 = 75
Total production in 1992 = 90
total change in production of all types of cars in 1993-91 = Total production in 1992 - Total production in 1991 = 90 - 75 = 15
Required percent increase = | total change in production of all types of cars in 1993-91 | x 100% |
total production of all types of cars in 1991 | ||
= | 15 | x 100 = 20 % |
75 | ||
