Answer:

The efficiency of the machine is 40 %.

Explanation:

We have,

Output work by the machine is 4 joules and the input work is 10 joules.

It is required to find the efficiency of a machine. The efficiency of a machine is given by the ratio of output work to the input work. It is given as :

\eta=\dfrac{4}{10}\times 100\\\\\eta=40\%

So, the efficiency of the machine is 40 %.
