Question 859415
<pre>
Jill is twice as old as Jim. Jim is three years older than Ken .The sum of their ages is 61. What are their their ages?

Let Ken's age be x
Then Jim's age is x + 3
And Jill's age is 2*(x + 3) = 2*x + 6
Sum of ages = {{{x + x + 3 + 2*x + 6 = 4*x + 9 = 61}}}
Simplifying {{{4*x = 52}}} or {{{x = 13}}}
So Ken's age is {{{highlight(13)}}}, Jim's age is {{{highlight(16)}}} and
Jill is {{{highlight(32)}}}
Check: Sum = 13 + 16 + 32 = 61. Correct!
Hope you got it :)
