Answer:
Total number of pensioners = 40
Step-by-step explanation:
Given:
Ratio for children to adult = 1 : 2
Ratio of adults to pensioners = 3 : 4
Total number of seats = 85
Find:
Total number of pensioners
Computation:
Common ration of children to adult to pensioners
1.5 : 3 : 4
In simple form
3 : 6 : 8
Total number of pensioners = Total number of seats [(8)/(3+6+8)]
Total number of pensioners = 85[(8)/(17)]
Total number of pensioners = 40
