Code is taking half of my input

I am in a programming class to learn C++. We had to work on a if and else statement problem. Below is my code, and I am trying to figure out why it is halving it.

#include <iostream>
#include <iomanip>

using namespace std;

int main() {

   int age;
   double price;
   char category;
   double finalPrice;

   cin >> price;
   cin >> age;
   cin >> category;

if (age <= 0) {
   cout << "Wrong input";
   }
if (age > 0 && age <= 5) {
   if (category != 'A' || 'a') {
      finalPrice = price - (( price * 100)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }

else if(category == 'A' || 'a') {
      finalPrice = price - (( price * 0)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
}

if (age > 5 && age <= 12) {
   if (category != 'B' || 'b') {
      finalPrice = price - (( price * 50)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
else if(category == 'B' || 'b') {
      finalPrice = price - (( price * 0)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
      }   
   }

if (age > 12 && age <= 26) {
   if (category != 'C' || 'c') {
      finalPrice = price - (( price * 60)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
else if(category == 'C' || 'c') {
      finalPrice = price - (( price * 0)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
      }      
}

if (age > 26 && age <= 60) {
   if (category != 'D' || 'd') {
      finalPrice = price - (( price * 70)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
else if(category == 'D' || 'd') {
      finalPrice = price - (( price * 0)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
}

if (age > 60) {
   if (category != 'E' || 'e') {
      finalPrice = price - (( price * 80)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
   }
else if(category == 'E' || 'e') {
      finalPrice = price - (( price * 0)/100);
      cout << fixed;
      cout << setprecision(2) << finalPrice;
      }      
}

return 0;
}

So above is my code for a assignment for school.

When I enter the values 14.56 25 C I get an output of 5.8.2

However my expected output should just be 14.56

Am I just overseeing something? I don't get how it is even getting half.

Thanks!
