If we take the number of students in Parrot room as X
then in nightingle room the number of students will be 4x
then in Peacock room the number of students will be 4x+6
so as per the sum the total no of students is 60
Hence x+4x+4x+6 = 60
9x+6= 60
9x = 60-6 = 54
hence x = 54/9 = 6
So no of students in Parrot room = 6
no of students in Nightingale room = 6*4 = 24
no of students in Peacock room = 24+6 = 30
