Question

the tree planted by Kabir is 3m high. Every month the height of the tree increases by 0.1 m. After how many months will the tree be 7/2 m tall

Answer 1

350 months tree height is 7/2

Answer 2

Answer:

5 months

Step-by-step explanation:

Given : The tree planted by Kabir is 3m high. Every month the height of the tree increases by 0.1 m.

To Find : After how many months will the tree be 7/2 m tall

Solution:

Height of the plant is 3 m.

Every month the height of the tree increases by 0.1 m.

Let x be the number of months after which the tree will be $\frac{7}{2}$  m tall

So, increase in height in x months = 0.1 x

So, total height after x months = 3+0.1x

So, $3+0.1x =\frac{7}{2}$

$6+0.2x =7$

$0.2x =1$

$x =\frac{1}{0.2}$

$x =5$

Hence After 5 months the tree will  be 7/2 m tall.
