Question

You were playing a fun guessing game during your school break. There were a total of 100 participants excluding you. Out of these 100 people, 30 were Maths Majors, 45 were Economics Majors and 25 were Physics Majors. The game was divided into three rounds. • In the first round, you had to guess the number of Maths Majors and you correctly guessed 20 of them. In the second round, you had to guess the number of Economics Majors and you correctly guessed 30 of them. . In the final third round, you had to guess the number of Physics Majors and you correctly guessed 20 of them. Accuracy is defined as the number of correct guesses upon total number of people in the group (expressed in percentage)​

Answer 2

Given,

There were a total of $100$ participants excluding you.

Out of these $100$ people, $30$ were Maths Majors, $45$ were Economics Majors and $25$ were Physics Majors & the game was divided into three rounds.

First-round no. of Maths Major guess $= 20$ out of $30$

Second-round no. of Economics Majors$=30$ out of $45$

Third-round no. of Physics Majors$=20$ out of $25$

As, Accuracy is defined as the number of correct guesses upon total number of people in the group.

For Maths Major Accuracy is $=\frac{20}{30}$×$100$$=66.67$%

For Economics Major Accuracy is$=\frac{30}{45}$×$100$$=66.67$%

For Physics Major Accuracy is $=\frac{20}{25}$×$100$$=80$%

So, Physics Majors were guessed more accurately than Maths & Economics Majors.
