Question

In a classroom, of the students are wearing blue shirts, and are wearing white shirts. There are 36 students in the class. How many students are wearing a shirt other than blue or white? 0 24 students O 30 students 5/6 students 6 students

Answer 1

In a classroom, The total number if students in the class = 36

1/6 of the students wearing blue shirt

i.e. 1/6 of 36 students wearing blue shirt :

$\begin{gathered} \frac{1}{6}\text{ of 36 = }\frac{1}{6}\times36 \\ \frac{1}{6}\text{ of 36 =6} \end{gathered}$

So, Number of students wearing blue shirts = 6

2/3 are wearing white shirts

i.e. 2/3 of 36 students wearing white shirt :

$\begin{gathered} \frac{2}{3}\text{ of 36 =}\frac{2}{3}\times36 \\ \frac{2}{3}\text{ of 36 =24} \end{gathered}$

Number of students wearing white shirts = 24

Number of students wearing white shirt or blue shirt = 24 + 6

Number of students wearing white shirt or blue shirt = 30

Number of students not wearing white shirt or blue shirt = Total number of students - Number of students wearing white shirt or blue shirt

Number of students not wearing white shirt or blue shirt = 36 - 30

Number of students not wearing white shirt or blue shirt = 6

So, Number of students are wearing a short other than white or blue is 6

Answer : D)

Number of students are wearing a short other than white or blue is 6
