Adult : Children
3 : 5
After 6 adults and 4 children
The ratio is 3:4
The ratio of adult didn't change which indicates that the 6 adults are splited into groups of 2.
The children on the other hand are splited into group of 1. However, ratio is reduce by 1 which mean that the last group is further splitted.
From the adult graph, we can conclude that the last group contain 4 children. Hence one unit contain 4 people.
However the new unit contain 4+2 = 6 people.
3+4 = 7 units
7 units = 7 x 6 people
=42 people on the bus
