Given:

Velocity ratio = Number of pulleys (n) = 3

Effort raised = 50  N

Load = 150  N

To find:

The efficiency of the pulleys

Formula used:

Mechanical advantage = \frac{Load}{Effort}

Efficiency =  \frac{Mechanical advantage}{Velocity ratio} ×  100 %

Step-by-step explanation:

Mechanical advantage =  \frac{150}{50} = 3

Efficiency = \frac{3}{n}  = \frac{3}{3} × 100 %  = 100%

Answer:

The efficiency of the pulley is 100 %
