A 2500

B 25000

C 350000

D 3500000

E None of these

Solution

Correct Answer: Option C

Average number of Computers manufactured by all the Companies together = (Total number of computers manufactured by all the companies)/(Total number of companies) = (10 + 15 + 7.5 + 22.5 + 30)/5 = 85/5 = 17 lakhs

Average number of Computers sold by all the Companies together = (Total number of computers sold by all the companies)/(Total number of companies) = (7.5 + 12.5 + 5 + 17.5 + 25)/5 = 67.5/5 = 13.5 lakhs

Require Difference = (17-13.5) Lakhs = 3.5 Lakhs = 350000
