Answer:

The output is 225N

Explanation:

The formula for calculating the efficiency of the pulley can be given as

[tex]E = \frac{output}{input} \times 100\%[/tex]

The input is 300N and the efficiency of the pulley is 75%.

Making output the subject.

[tex]output = \frac{E}{100\%} \times input[/tex]

Substituting the value.

[tex]output = \frac{75}{100} \times 300 = 225N[/tex]
