Question

After a storm, 135 trees out of 180 were left standing. What is the percentage loss of the number of trees?

Answer 1

Percentage loss of the number of trees is
`25\%`.

Explanation:

Given: After a storm,
`135` trees out of
`180` were left standing.

To find: What is the percentage loss of the number of trees?

Solution:

We have,

Total number of trees
`=180`

Number of trees left standing
`=135`

Therefore, loss of trees
`=180-135=45`

We now that
`\text {Loss\%}=\frac{\text{Number of trees left}}{\text{Total number of trees}}* 100 \%`

`\implies \text {Loss\%}=(45)/(180)* 100 \%`

`\implies \text {Loss\%}=(450)/(18) \%`

`\implies \text {Loss\%}=25 \%`

Hence, the percentage loss of the number of trees is
`25\%`.
