The number of people to play the arcade or board games.

Answer to Problem 16PPS

  $225$ and $275$ number of people will play the Arcade or board game respectively.

Explanation of Solution

Given:

No of people participated in the study: $N=2500$

Concept Used:

Number of people to play the type of game is expressed by using the following expression:

  $N_i=\frac{P_i}{100}\times N$

Where,

No of people participated in the study: $N$

The percentage of people for the specific game as per the given figure: $P_i$

Calculation:

Number of people to play the Arcade game is calculated as

  $\begin{array}{l}{N}_A=\frac{P_A}{100}\times N\\ N_A=\frac{9}{100}\times 2500\\ N_A=225\end{array}$

Number of people to play the Board game is calculated as

  $\begin{array}{l}{N}_B=\frac{P_B}{100}\times N\\ N_B=\frac{11}{100}\times 2500\\ N_B=275\end{array}$

Conclusion:

Hence, out of $2500$ ; $225$ and $275$ number of people will play the Arcade or board game respectively.
