problema con uncodigo

hola tengo problemas con un codigo yo lo tengo de una forma pero mi profesor me dice que hay otra forma de hacerlo y mas corto pero no encuentro la forma y tambien tengo problemas tengo que multiplicar la tercer columna y dividirla por el numero que sale hasa abajo y dice resultado de la suma solo que no puedo me sale a la hora de ejecutarlo me sale solo (inf).
dejo mi codigo lo estoy corriendo en dev c++
espero puedan ayudarme llevo 2 dias tratando de hacerlo
