Harry is twice as old ad his friend Jones.
Jones is five years older than Mel.
In five years, Harry will be three times as old as Mel.
How old is Jones now?
Express your answer in months
~~~~~~~~~~~~~~~~~
Let x be the Jones' age.
Then Harry is 2x years old, while Mel is (x-5) years old, according to the condition.
Further, in 5 years, Harry will be (2x+5) years old, while Mel will be ((x-5) + 5) = x years old.
So, we write an equation as we read the text
2x+5 = 3x.
From this equation, x = 5.
So, the problem is just solved, and you get the
ANSWER. x = 5, i.e. Jones' current age is 5 years.
Solved.
The instruction to present the answer in months looks to be strange and irrelevant.
But you can do it by multiplying 5 years by 12 months, if you wish.
