Answer 2

Answer:

C) a+3

Step-by-step explanation:

We are given the following data:

Tom's Age:  10  11  12  a

Kim's Age:   13  14  15  

We have to evaluate Kim's age when Tom's age is a.

We have to build a relationship between Tim's age and Kim's age. If we look at their ages carefully we can see a pattern and their relation can be described as:

$\text{Kim's age = Tim's age + 3}$

Thus, when Tim's age is a, we can compute Kim's age as:

$\text{Kim's age = a + 3}$
