Answer:
Let M represents Maria's height, N represents Nancy's height, B represents Brad's height and C represents Chad's height.
Note : all heights are in inches.
Given,
M < N
Such that M = N - 11,
B < C,
Such that, B = C - 11,
M < B,
⇒ M < B < C,
Thus, there is the less information to compare the height of Nancy and Chad.
If M = B,
Then M = C - 11 ⇒ C = M + 11
But N = M + 11
⇒ C = N
Thus, if Maria and Brad are the same height then the height of Nancy and Chad will same.
