Hint : Believer is a machine that consists of a bar or plane pivoting on a fulcrum, lever have three main parts. load, fulcrum and the effort. The load is the object that is to be moved, the fulcrum is the point of which the liver pivots. The effort is the force that is used to move the lever.
Third class lever:-
In a third class lever the effort is between the load and the fulcrum. Some examples of the third class lever include fishing rod, cricket bats and chopsticks. Third class levers are different from first and second class levers.

Complete solutions:-
By decreasing the distance between the effort and load point in class 3 lever, the fulcrum is at one end, load point is at the other end and effort point lies in between the two. The effort arm is less the load arm
${\text{MA = }}\dfrac{{{\text{Effort arm}}}}{{{\text{Load arm}}}} \prec {\text{1}}$${\text{MA = }}\dfrac{{{\text{Effort arm}}}}{{{\text{Load arm}}}} \prec {\text{1}}$
To increase the MA the effort arm must be made to approach as close as it possible to the load arm. This is done by moving the effort point closer to the load point.
