Answer:

D. 16 years old

Explanation:

Step 1: Let T be Tien's age and J as Jordan's age (today),


T=(1)/(4)J

Step 2: Let T be Tien's age and J as Jordan's age (in 2 years),


T+2=(1)/(3) (J+2)


T=(1)/(3)(J+2)-2

Step 3: As their age differences will always be similar we can have the two equations above equal to find Jordan's age,


(1)/(4) J=(1)/(3)(J+2)-2\\(1)/(4)J-(1)/(3)J=(2)/(3) -2 \\-(1)/(12)J= -(4)/(3) \\\\J=16
