• A. 3500
• B. 35000
• C. 350000
• D. 3500000
• E. None of these

Answer 1

The correct option is C 350000

Average number of computers manufactured by all the companies together,
$=\left(\frac{10+15+7.5+22.5+30}{5}\right)lakhs$
$=\left(\frac{85}{5}\right)lakhs$ = 17 lakhs
Average number of computers sold by all the companies together,
$=\left(\frac{7.5+12.5+5+17.5+25}{5}\right)lakhs$
$=\left(\frac{67.5}{5}\right)lakhs$ = 13.5 lakhs
$\therefore$ Required difference = (17-13.5)lakhs
= 3.5 lakhs = 350000
