Answer: If 1 pair of socks = 4 and 1 shirt = 10 then your answer will be C, 14.
Explanation: in the beginning it says ONE PAIR OF SOCK AND 2 SAME SHIRT =24. One sock=4 and 2 shirts=20 , 20 + 4 = 24. Solved.
Then 3 pairs of socks (4 x 3 = 12) and 2 of the same shirts (10 + 10 = 20) then 20 + 12 = 32!!
