Question

Production of a company A is 120 % of the production of company B and 80 % of the production of company C. What is the ratio between production of companies A, B and C respectively?

• A. 6 : 5 : 9
• B. 6 : 5 : 4
• C. 12 : 10 : 15
• D. 10 : 12 : 15

Answer 1

Answer: (C)

12 : 10 : 15

Let the production of company B=100

Then production of company A =120

$\therefore$ Production of company C $=\frac{120}{80}100=150$

Then $A:B:C=120:100:150\Rightarrow 12:10:15$
