Correct Answer - Option 1 : Reena is youngest
i. A * B means -> A and B are of the same age
ii. A - B means -> B is younger than A → A is older than B
iii. A + B means -> A is younger than B
Sachin * Madan - Reena means?
Sachin = Madan > Reena means Reena is the youngest.
Hence, ‘Reena is youngest’ is the correct answer.
