Question

Number of pizzas purchased during a five-month period in 1991 and in 1992 are shown below. Find out the difference in total production of pizzas in the year 1991 and 1992.

Answer 1

From the Joint Bar graph,

Total production of pizzas in the year 1991 is:
= 8000 + 7000 + 13000 + 10000 + 12000 = 50000

Total production of pizzas in the year 1992 is:
= 11000 + 10000 + 12000 + 14000 + 13000 = 60000

Difference in the production = 60000 - 50000 = 10000
