A, B and C often eat dinner out. Each orders either tea or coffee after dinner.

i) If A orders coffee, then B orders the drink that C orders.

ii) If B orders coffee, then A orders the drink that C does not order.

iii) If C orders tea, then A orders the drink that B orders.

Who do you know always orders the same drink after dinner?

Option (D) From I and II, we conclude that Mathematics period began at 9.00 a.m., Biology period began at 8:00 a.m. and Physics period began at 11 a.m. So, the Chemistry period began at 10:00 a.m.

From I and III, we conclude that Mathematics period ended and Chemistry period began at 10:00 a. m.

A/c to condition – I = 3 & 6 are eliminated.

A/c to condition – II = 1 is eliminated.

A/c to condition – III = 2 is eliminated .

left out is 4 & 5

Out of 4 & 5, Only A orders the same drink.
