Question

In a garden 10% of the trees were uprooted due to decay, 180 trees are left there, the total number of trees are

• A. 170
• B. 190
• C. 200
• D. 210

Answer 1

The correct option is C 200

Let the total number of tree = $x$
Trees uprooted = 10 % = $\frac{10}{100}\times x=\frac{x}{10}$
Now, trees left = $x-\frac{x}{10}=\frac{9x}{10}=180$
$x=\frac{1800}{9}=200$
Thus, total number of trees are 200
