Answer 2

Given: THE COST OF HOUSE INCREASE 20% WITHIN A 1 YEAR

To find: HOW LONG WILL IT TAKE TO DOUBLE

Solution:

Let the cost of the house be equal to x. According to the question, the time taken by the cost of the house to increase by 20% is one year. Thus, the increased cost can be written as follows.

$x+(\frac{20}{100}*x)= \frac{12}{10}x$

                    $=\frac{6}{5} x$

The double of the cost of the house can be written as 2x. Now, in order to calculate the time taken for the cost of the house to double, the following calculations are done.

$\frac{2x}{\frac{6}{5}x } = \frac{10}{6}$

     $= \frac{5}{3}$

     $= 1.67$

So, it takes 1.67 years for the cost of the house to double.

Therefore, it will take 5/3 or 1.67 years to double.
