Number of Computers Manufactured and Sold by Various Companies in a Year (Number in Lakhs)

Question 147

What is the difference between the average number of computers manufactured by all the companies together and the average number of computers sold by all the companies together ?

Solution

Total number of computers manufactured by all the companies together

= 10 + 15 + 7.5 + 22.5 + 30 = 85 lakhs

Total number of computers sold by all the companies together 

= 7.5 + 12.5 + 5 + 17.5 + 25 = 67.5 lakhs

Difference = 85 - 67.5 = 17.5 lakhs

=> Required average = $$\frac{17,50,000}{5} = 3,50,000$$
