Out of the number of vehicles manufactured by the company 'P' in 2013, 15000 pieces were found defective and out of the number of vehicles manufactured by the company 'Q' in 2014, 10000 pieces were found defective. What is the respective ratio of non-defective vehicles manufactured by the company 'P' in 2013 and Q in 2014?

• A. 9 : 8
• B. 11 : 4
• C. 3 : 8
• D. 5 : 8
• E. 7 : 4

Answer 1

The correct option is A 9 : 8

Total vehicles produced by P in 2010 = 240 thousands
Defective = 15 thousands
Non - defective = 225 thousands
Total vehicles produced by Q in 2013 = 210 thousands
Defective vehicles = 10000
Non - defective = 200 thousands
Ratio = 225 : 20 = 9 : 8
