Given:

The principal approved the event for 200 students.

The number of juniors should be 25% of the number of seniors.

To find:

The number of juniors.

Step-by-step explanation:

Let x be the number of seniors.

According to the problem,


x+25\%\text{ of }x=200

Solve for x we get,


\begin{gathered} x+(25)/(100)x=200 \\ x+(1)/(4)x=200 \\ (5x)/(4)=200 \\ 5x=800 \\ x=(800)/(5) \\ x=160 \end{gathered}

So, the number of seniors is 160.

Therefore, the number of juniors must be,


200-160=40

Final answer:

The number of juniors is 40.
