Para resolver el problema "Hallar el 15% de los 2/3 de 5/8 del 8% de 4 × 10^4", debemos seguir una serie de pasos detallados:

1. Calcular el 8% de \(4 \times 10^4\):
\(4 \times 10^4 = 40000\)

El 8% de 40000 se calcula como:
[tex]\[ 0.08 \times 40000 = 3200 \][/tex]

2. Calcular \(5/8\) de 3200:
El \(5/8\) de 3200 se calcula como:
[tex]\[ \frac{5}{8} \times 3200 = 2000 \][/tex]

3. Calcular \(2/3\) de 2000:
El \(2/3\) de 2000 se calcula como:
[tex]\[ \frac{2}{3} \times 2000 = 1333.33 \][/tex]

4. Calcular el 15% de 1333.33:
El 15% de 1333.33 se calcula como:
[tex]\[ 0.15 \times 1333.33 = 200 \][/tex]

Por lo tanto, el resultado final es 200. La respuesta correcta es:

B) 200
