Jack is now 14 yrs older than Bill
j=b+14

in 10 yrs
j+10=2(b+10)
so
b=4 that means j=18 and in 5 years he will be 23 .Hence D.

Just wondering, what does it mean by 'If in 10 years Jack will be twice as old as Bill' ? I mean, what is it indicating ? 'as old as Bill' IS/WILL BE ?, if we consider Bill 'IS', then equation might be changed to J+10=2b, Correct me what to consider, 'IS' or 'WILL BE'? Appreciate help.

'If in 10 years Jack will be twice as old as Bill' means that after 10 years from now, jack will be twice as old as Bill.

The equation will be (J+10) = 2(B+10). Because, even Bill will be +10 years old after 10 years from now. I don't understand your doubt reg is/will be.

Thanks papgust!, what I'm saying whether actual question "Jack is now 14 years older than Bill. If in 10 years JAck will be twice as old as Bill, how old will JAck be in 5 years? " is meaning as:

Jack is now 14 years older than Bill. If in 10 years JAck will be twice as old as Bill [spoiler]is of now[/spoiler], how old will JAck be in 5 years?

or

Jack is now 14 years older than Bill. If in 10 years JAck will be twice as old as Bill will be, how old will JAck be in 5 years?

I know it's very simple thing, but exploring all those meaning, if they really could make any sense!

Ok. Now i get it. It should be the second one.

"is of now" implies Bill's current age and not the age 10 years from now. Question clearly says that "If in 10 years JAck will be twice as old as Bill". The 10 years calculation includes both Jack and Bill.

Hope i've answered your query.

Hi All,
Could anyone show me how to solve this using a chart, i.e. The MGMAT way?

Thanks,
D

Jack is now 14 years older than Bill. If in 10 years JAck will be twice as old as Bill, how old will JAck be in 5 years?

a. 9
b.19
c.21
d.23
e.33
We can plug in the answers, which represent Jack's age in 5 years.

Answer choice C: Jack in 5 years = 21.
Jack's current age = 21-5 = 16.
Bill's current age = 16-14 = 2.
Jack in 10 years = 16+10 = 26.
Bill in 10 years = 2+10 = 12.
Jack's age is not twice Bill's age.
Eliminate C.
Since the smaller answer choices will make Bill's age 0 or less, eliminate A and B.

Answer choice D: Jack in 5 years = 23.
Jack's current age = 23-5 = 18.
Bill's current age = 18-14 = 4.
Jack in 10 years = 18+10 = 28.
Bill in 10 years = 4+10 = 14.
Success! Jack's age is twice Bill's age.

The correct answer is D.

Thanks for the response... is their a table method for this though?

NOW || 5 YEARS || 10 YEARS ||
Bill J - 14 || J - 9 || J + 10/2||
Jack J || J + 5? || J + 10 ||
TOTAL 2J - 14 || 2J - 4 || 3J + 3 ||

Something along those lines?
