In a class room 3/10 of the students are wearing blue shirts and 3/5 are wearing white shirts there are 20 students In The class
shtirl [24]

Total number of students in the class = 36

Number of students wearing blue shirts = (1/6) * 36

                                                                = 36/6

                                                                = 6

Number of students wearing white shirts = (2/3) * 36

                                                                 = 2 * 12

                                                                 = 24

Then

Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)

                                                                                                       = 36 - 30

                                                                                                       = 6

So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
