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 =
Simplifying or
So Ken's age is , Jim's age is and
Jill is
Check: Sum = 13 + 16 + 32 = 61. Correct!
Hope you got it :)
