let the total no of people be x
so no of adults = 3x/8
⇒ Number of children = 5x/8
According to the question 5x/8 - 3x/8 = 90
⇒ x/4 = 90
⇒ x = 90 × 4
x = 360
Hence number of children = 5 × 360/8 = 225
so no of adults = 3x/8
⇒ Number of children = 5x/8
According to the question 5x/8 - 3x/8 = 90
⇒ x/4 = 90
⇒ x = 90 × 4
x = 360
Hence number of children = 5 × 360/8 = 225
