The Robinsons have had three children of different ages. How old is the youngest today?
(1) The two older children have, together, 16 years
(2) The two younger children have, together, 9 years
Let:
y = the youngest child.
m = the middle child.
e = the eldest child.
Both statements are satisfied by the following cases:
y=4, m=5, e=11.
y=3, m=6, e=10.
Since y can be different values, the two statements combined are INSUFFICIENT.
The correct answer is
E.
