Question

The Claude crayon company can make 2400 crayons in 4 minutes. If each crayon box has 12 crayons, how many crayon boxes can they make in 15 minutes?

Options:

A . 750

B . 800

C . 900

D . 1000

Answer: Option A
:
A
Let n be the number of boxes.
As there are 12 crayons in each box, 2400 crayons fits into

\frac{2400}{12} = 200 b o x e s

Now the number of boxes produced will be directly proportional to time taken.

\frac{A}{B}

= Constant

\frac{A_{1}}{B_{1}}

\frac{A_{2}}{B_{2}}

\frac{N o . o f c r a y o n s b o x e s}{t i m e} = \frac{200}{4} = \frac{n}{15}

So, n = 750
