Amount of Interest=7152-6400=752=I

  • Principal=6400=P
  • Rate of interest=6%=R
  • Time=T=?

We know

\boxed{\sf I=\dfrac{PRT}{100}}

\\ \sf\longmapsto T=\dfrac{PR}{100I}

\\ \sf\longmapsto T=\dfrac{6400(6)}{100(752)}

\\ \sf\longmapsto T=\dfrac{38400}{75200}

\\ \sf\longmapsto T\approx 0.5year

\\ \sf\longmapsto T\approx 6months

Ayuda, no le entiendo :)

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.

<h3>¿Cuántos dias tardarán en fabricar 3000 ruedas si trabajan 10 horas diarias?</h3>

Sabemos que trabajando 8 horas, en 5 dias producen 2000 ruedas.

El número total de horas que trabajan en esos 5 dias es:

(8 horas)*5 = 40 horas

Entonces se producen 2000 ruedas en 40 horas, es decir, la razon de trabajo es:

(2000 ruedas)/(40 horas) = 50 ruedas por hora.

Ahora, sí en la fabrica trabajan 10 horas al día, entonces van a producir:

10h*(50 ruedas por hora) = 500 ruedas por día.

El número x de días que deben trabajar para producir 3000 ruedas es:

x*(500 ruedas por dia) = 3000 ruedas

x = (3000 ruedas)/(500 ruedas por dia) = 6 dias.

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.
