Question

Si el 20% del 30% de N sumado al 80% del 40% de 2N es iguala N disminuido en el 60% de 240,
Calcule el valor de N.

Answer 1

Respuesta:

480

Explicación paso a paso:

(20%)*(30%)*(N) + (80%)*(40%)*(2*N) = N - (60%)*(240)

(20/100)*(30/100)*(N) + (80/100)*(40/100)*(2*N) = N - (60/100)*(240)

(3/50)*(N) + (8/25)*(2*N) = N - 144

(7/10)*N = N - 144

144 = N- (7/10)*N

144 = (3/10)*N

(144)*(10/3) = N

480 = N
