Let's assume
total number of tourists is x
now, we can find percentage of children
[tex] children=100-female-male [/tex]
[tex] children=100-35-45 [/tex]
[tex] children=20 [/tex]
so,
20% of tourists is children
so, we get
[tex] \frac{20}{100} *x=14 [/tex]
now, we can solve for x
[tex] x=14*5 [/tex]
[tex] x=70 [/tex]
so,
total number of tourists is 70.........Answer
