B = 13P.

9 Years from Now, B+9 = 4(P+9)

Solving we get P = 3.

2 years from now Pete will be 3+2 = 5.

C is the answer.

Let Pete's present age is x.
In Nine years Pete's age will be x+9
Bill is thirteen times as old as Pete. So, Bill's age=13x
in 9 years Bill's age will be 13x+9
To find: x+2

Given, In nine years, Bill will be four times as old as Pete
So, 4(x+9)=13x+9
Or, x=3
So, x+2=3+2=5
Ans. (C)

A. 3
B. 4
C. 5
D. 6
E. 7



2 scenarios here:

Present:

Pete = p

B= 13p

Future( in 9 years) :

B + 9 = 4( P + 9)

13P + 9 = 4P + 36

9P = 27

P = 3.

Question: Age of Pete after 2 Years.

Present age of Pete = 3

So, Pete will be 5 years old after 2 years.

The best answer is C.

Hi,

For age-word problems, try drawing a table with rows and columns as objects(persons) and time period,

Find below the diagram for the table method to solve such questions.

You can see the answer is 5. Option C.

Table method is nothing different, it just gives a clear picture and avoid confusions when using different time periods.

hope its clear.
