Question 1103903

<pre>
According to the condition, Leslie is 17.


Hence, three times the age of Vin is 17+1 = 18.


Then the age of Vin is {{{18/3}}} = 6.


Kwame is 2*6 = 12 years old.

Honestly, I do not understand for what reason this problem was posted to the forum.


All you need to solve it is an ability to read English and understand the words.
