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.



In the year 2019, if production of shoes of type A and B decreases by 10% and 20% respectively while production of shoes of type C increases by 25% with respect to the previous year, then find the total number of shoes produced in the year 2019.

Answer 1

In the year 2019:

Number of shoes of type A produced = $9000\times \frac{90}{100}=8100$

Number of shoes of types B produced = $6000\times \frac{80}{100}=4800$

Number of shoes of type C produced = $10000\times \frac{125}{100}=12500$

Required total = 8100 + 4800 + 12500 = 25400

Hence, 25400 is correct.
