Let ‘W’ be the amount of hot-dogs eaten by winner
And ‘T’ be amount of hotdogs eaten by Third place

St1:

W=T+24 -------(1)  Insufficient

St2 :

Rate X Time = Work

Rate(W) = W/t

Rate(T) = T/t

W/t = 2 T/t

Therefore, W = 2T ---------- (2)  Insufficient




From (1) and (2)

2T = T+24

T=24 and W=48


Hence C
