2️⃣ 40
3️⃣ 80
4️⃣ 100​

Answer 1

The correct option is (3) 80. There are 80 other trees.

Given,

There are 100 trees in a garden. 1/5 of them are mango trees.

To Find,

How many other trees are there?

Solution,

We can solve the question as follows:

It is given that there are 100 trees in a garden. 1/5 of them are mango trees. We have to find the remaining number of trees.

$Total\: number\: of\: trees =100$

The total number of mango trees will be equal to 1/5 of 100. Therefore,

$Number\: of\: mango\: trees = \frac{1}{5} *Total\: number\: of\: trees$

                                      $= \frac{1}{5} *100 = 20$

Now, the remaining number of trees will be equal to the number of mango trees subtracted from the total number of trees.

$Number\: of\: other\: trees = Total\: trees - mango\: trees$

                                    $= 100 - 20$

                                    $= 80$

Hence, there are 80 other trees.
