Question

A machine fills $420$ bottles in $3$ hours. How many bottles will it fill in $5$ hours?

• A. $252$
• B. $700$
• C. $504$
• D. $300$

Answer 1

Answer: (B)

$700$

If more number of bulbs required then, time taken will also be more. Therefore it's directly proportional.

Let us consider the bottles be $x$, then

$420/3=x/59$

$3\times x=420\times 5$
$3x=2100$
$x=2100/3$

$x=700$

$\therefore 700$ bottles can be filled.
