5 0

Usando el concepto de porcentaje, se encuentra que 15% faltaron, opcion D.

------------------

La porcentage de una medida a sobre un total b es dada por:

P = \frac{a}{b} \times 100\%

------------------

En esta pregunta, tenemos que

  • Total de 1280 alumnos, o sea b = 1280.
  • 1088 salieron, entonces, 1280 - 1088 = 192 faltaron, o sea, a = 192.

La porcentaje dos que falton es de:

P = \frac{192}{1280} \times 100\% = 15\%

O sea, la respuesta correcta es dada por opcion d.

Ede4ka [16]
Since we are looking for the principal amount, then all we have to do is reverse the process of getting the amount of tax. In order to get the principal, you just have to divide 22 with 0.05. The answer is 440 so that is the principal amount you are looking for.
