Question

A shop has $600$ shirts and $400$ trousers, out of which one-fourth are defective. What percentage of trousers are good?

Answer 1

Here given that, There are $400$ trousers, out of which one-fourth are defective,

So, defective trousers are $400\times \frac{1}{4}=100$

So, the good trousers = $400-100=300$

Now, the percentage of good trousers= $\frac{300}{400}\times 100\%=75\%$

Hence, $75\%$ percentage of trousers are good
