Answer 1

Answer:

Option c) 12:10:15

Step-by-step explanation:

let the production of company c be x

production of company a=x*80/100=4x/5

production of company a=120/100=6/5 of production of company b

4x/5=6/5 of production of company b

production of company b=4x/6

equating the denominators

production of company a=24x/30

production of company b=20x/30

production of company c=30x/30

hence the ratio between the production of companies=24:20:30

=12:10:15
