Question

9) A machine fills 390 bottles of soda in 6 hours. How long will it take to fill 1365 bottles? ​

Answer 1

Answer:

21 hours is right answer

Step-by-step explanation:

$time \: taken \: to \: fill \: 390 \: bottles \: with \: soda = 6 \: hours \: \\ bottles \: which \: can \: fill \: in \: one \: hours \: = \frac{390}{6} \\ = 65 \\ time \: taken \: to \: fill \: 1365 \: bottles \: = \frac{1365}{65} \\ 21 \\ hence \: workers \: will \: fill \: 1365 \: bottles \: in \: 21 \: hours$
