Read the following pie charts carefully and answer the questions given below

Given the pie chart (I) shows the total numbers of shoes (Sports and Sneakers) sold by five different shops in 2020. Given pie chart (II) shows the total numbers of Sneakers shoes sold by five different shops in 2020.

What is the average number of sports shoes sold by shop A and B together?

The correct answer is 630.

Based on the provided pie charts:

Pie Chart (I) - Total number of shoes (Sports + Sneakers) = 8000

Distribution for Shops A and B:

• Shop A = 20% of 8000

• Shop B = 15% of 8000

Pie Chart (II) - Total number of Sneakers shoes = 4400

Distribution for Shops A and B:

• Shop A = 15% of 4400

• Shop B = 20% of 4400

Step 1: Calculate the total number of shoes sold by shop A and shop B.

Total shoes sold by shop A:

$\text{Shop A (Total)}=20\%\text{ of }8000=\frac{20}{100}\times 8000=1600$

Total shoes sold by shop B:

$\text{Shop B (Total)}=15\%\text{ of }8000=\frac{15}{100}\times 8000=1200$

Step 2: Calculate the number of sneakers shoes sold by shop A and shop B.

Sneakers sold by shop A:

$\text{Shop A (Sneakers)}=15\%\text{ of }4400=\frac{15}{100}\times 4400=660$

Sneakers sold by shop B:

$\text{Shop B (Sneakers)}=20\%\text{ of }4400=\frac{20}{100}\times 4400=880$

Step 3: Calculate the number of sports shoes sold by shop A and shop B.

Since Total Shoes = Sports Shoes + Sneakers Shoes:

$\text{Sports Shoes}=\text{Total Shoes}-\text{Sneakers Shoes}$

Sports shoes sold by shop A:

$\text{Shop A (Sports)}=1600-660=940$

Sports shoes sold by shop B:

$\text{Shop B (Sports)}=1200-880=320$

Step 4: Find the average number of sports shoes sold by shop A and B together.

Total sports shoes sold by shop A and B together:

$\text{Total Sports Shoes (A + B)}=940+320=1260$

Average number of sports shoes sold by shop A and B together:

$\text{Average}=\frac{1260}{2}=630$
