Each pulley reduces the extra effort compulsory to lift the
elephant (light and 100% efficiency). If the elephant "weighs" 27,800
N and the person can apply 700 N,
27,800 / 700 = 39.7 which is about 40 N.
The answer that offers a combined # of 40 pulleys is computed by:
40 / 2 = 20
Therefore the answer is 20 fixed and 20 moveable.
B) using a blood pressure monitor to find a patient's blood pressure.
