A. 6 : 15 : 21 : 16
B. 4 : 10 : 14 : 9
C. 9 : 16 : 24 : 20

Solution(By Examveda Team)
Assume the total production of the first year as 10000, second year becomes 12000, third year 14400 and fourth year 17280. Then, 0.2 × 17280 - 0.2 × 12000 = 1056 But this difference is given as 2640. Hence, the value of production will be; 25000, 30000, 36000, and 43200 respectively for the 4 years. Ratio of revenue generated in 2002, = 2 × 3 : 4 × 5 : 2 × 7 : 2 × 8 = 6 : 20 : 14 : 16 = 3 : 10 : 7 : 8This Question Belongs to Data Interpretation >> Bar Chart
