Joan, Kylie, Lillian, and Miriam all celebrate their birthdays today. Joan is 2 years younger than Kylie, Kylie is 3 years older than Lillian, and Miriam is one year older than Joan. Which of the following could be the combined age of all four women today?

Here's how i have set the variables:
J = K - 2
K = L + 3
M = J + 1
Now if I assume Lilian is 10 years old
L = 10
K = 13
J = 11
M = 12
If we add the unit value comes to 6. I don't see it in the answer. Now I'm confused.
THanks

Translate in terms of Kylie = k
J = K-2
L = K-3
M = K-1
THUS THE FOUR AGES FORM A SET OF CONSECUTIVE INTIGERS WHOSE SUM IS 4K-6 = 2(2K -3)
THUS THE ANSWER IS EVEN...52 OR 54 ,SINCE 2K-3 ODD THUS DEVIDING THE ANSWER CHOICES BY 2 MUST GIVE AN ODD ANSWER
54 is my answer
