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
