Question 1065484
.
My age was 1/3 of my fathers' age {{{highlight(cross(before))}}} 18 years ago. Now my fathers' age is twice as my age. What is my age now?
~~~~~~~~~~~~~~~~~~~~~~~~


For me, this formulation does not seem to be perfect. Much better is this:


<pre>
     18 years ago, my age was 1/3 of my fathers' age. Now my fathers' age is twice as my age. What is my age now?
</pre>

The solution below corresponds to this formulation.


<pre>
Let M be my age now. 
Then my father's present age is 2M.

18 years ago

M - 18 = {{{(1/3)*(2M-18)}}}.

To solve it, multiply both sides by 3. You will get

3M - 54 = 2M - 18,

3M - 2M = 54 - 18,

M = 36.

<U>Answer</U>. My present age is 36 years.
</pre>
