Solution

Para resolver este problema, sigamos los siguientes pasos:

  1. Determinemos la posición de A desde la derecha:

    • A está en la posición 15 desde la izquierda.
    • Hay un total de 54 personas en la fila.
    • Por lo tanto, la posición de A desde la derecha es: 54−15+1=4054 - 15 + 1 = 40.

  2. Determinemos la posición de B desde la izquierda:

    • B está en la posición 20 desde la derecha.
    • Por lo tanto, la posición de B desde la izquierda es: 54−20+1=3554 - 20 + 1 = 35.

  3. Ahora, calculemos el número de personas entre A y B:

    • A está en la posición 15 desde la izquierda.
    • B está en la posición 35 desde la izquierda.
    • El número de personas entre A y B es: 35−15−1=1935 - 15 - 1 = 19.

Por lo tanto, la cantidad de personas sentadas entre A y B es 19.

La respuesta correcta es: 19.
