Answer: Option C is correct.
Would surely like to see you begin the problem solution yourself and to share what you have done.
Let the girl's age be J and the father's F.
J=5 and F=42 now.
In x years, the father will be twice as old as the girl.
We write that as F + x = 2( J + x), or 42 + x = 2( 5 + x)
Then 42 + x = 10 + 2x => x = 32
check: is 42+32 = 2(5+32)? Is 74 = 2(37)? YES.
The answer: "5 years from now."
You add the last numbers then the second to last and etc. but remember what you carry over if you carry over any. if youre just looking for the answer it is 144579
