Question 105 (i)

It takes 17 full specific type of trees to make one tonne of paper. If there are 221 Such trees in a forest, then
What fraction of the forest will be used to make
(a) 5 tonne of paper?
(b) 10 tonne of paper?

Answer 1

(a) 1 Tonne of Paper require = 17 trees
$\therefore$ 5 tonne of paper require $=17\times$ 5 trees $=85$ trees
Now, there are 221 trees in the forset .
So, 85 trees covers $=\frac{85}{221}$ fraction of forest
$=\frac{5}{13}$ fraction of forest
(b) Similarly 10 Tonne of paper require$=17\times 10$ trees = 170 trees
So, 170 trees cover = $\frac{170}{221}$ fraction of forest
$=\frac{10}{13}$ fraction of forest
