Step-by-step explanation:
Given that:
Total number of members who race = 18
Ratio of racers to divers = 6 : 2
To find:
Total number of members of the team = ?
Solution:
Given the ratio = 6 : 2
As per the ratio given, we can let the number of racers =
and
As per the ratio given, we can let the number of divers =

Answer:
34
Step-by-step explanation:
We have to calculate non perfect square between and
So,
Let
17=n
18=n+1
Non perfect square between two number can be calculated as :
2n
2× 17=34
Therefore there are 34 non perfect numbers between and
