Question
What is the total number of machines sold by all the
companies together? Following table shows the total number of Machines manufactured by five different companies and the cost price of the machines. The line graph shows the percentage of manufactured machines sold and percentage profit on each machine for all the five companies.Solution
Machine sold by company A = 10,000 × 10/100 = 1,000 Machine sold by company B = 12,000 × 30/100 = 3,600 Machine sold by company C = 8,000 × 35/100 = 2,800 Machine sold by company D = 10,500 × 15/100 = 1,575 Machine sold by company E = 13,000 × 50/100 = 6,500 ∴ Total number of machines sold by all the companies = 1,000 + 3,600 + 2,800 + 1,575 + 6,500 = 15,475
