Today Rose is twice as old as Sam and Sam is 3 years younger than Tina. If Rose, Sam, and Tina are all alive 4 years from today, which of the following must be true on that day?
I. Rose is twice as old as Sam
II Sam is 3 years younger than Tina
III. Rose is older than Tina
A. I only
B. II only
C. III only
D. I and II only
E. II and III only
I chose E.
My explanation:
Assume, R 50.
R=2S
So, S = 25
S = T-3
So, T = 28
After 4 years,
R = 54
S = 29
T = 32
They satisfy both II and III conditions. Let me know if I'm wrong.
