How does a pulley help to transfer 20 bags of cement to the higher place?
A pulley helps us lift 20 bags of cement to a higher place withless effort.
What is a pulley?
A pulley is a wheel on an axle or shaft that is designed to support movement and redirect tension. They are simple, yet powerful devices that can make small forces move large objects. Pulleys are used to make heavy work more manageable.

A pulley system makes it easier to lift an object than lifting the dead weight by hand. A single pulley essentially changes the direction of the pull or force applied. When a person uses two or more pulleys in a system, then the system also multiplies the force applied besides changing its direction. With one fixed and one movable pulley in a system, it essentially doubles the weight of the load you could lift without help from another person based upon the weight you can lift.
