Question

Study the following bar graph carefully and answer the given questions.

The bar graph given below shows the quantity of three different types of shoes (i.e., A, B, and C) produced (in hundreds) by a company in four different years.

Find the difference between the average number of type A shoes produced in years 2016 and 2018 and average number of type C shoes produced in years 2015 and 2017.

• A. 2500
• B. 2000
• C. 1500
• D. 1750

Answer 1

The correct option is B 2000

Average number of type A shoes produced in 2016 and 2018 =$\frac{5000+9000}{2}=7000$

Average number of type C shoes produced in 2015 and 2017 = $\frac{4000+6000}{2}=5000$

Required difference = 7000 – 5000 = 2000

Hence, option B is correct.
