Answer: 80
Step-by-step explanation:
Let the number of girls be x
Therefore, the number of boys will be: = x + 60
The ratio of boys to girls is 5:1. Using this and equating to the number of bits and girls will be:
5/1 = x + 60/ x
Cross multiply
5x = x + 60
5x - x = 60
4x = 60
x = 60/4
x = 15
Number of girls = 15
Therefore boys will be: = x + 60 = 15 + 60 = 75.
Total number of people = 15 + 75 = 80
