A bucket full of water is kept in a room and it colls from 75°C to 70°C in time T, minutes, from 70°C to 65°C in time T2 minutes, and from 65°C to 60°C in time T3 minutes, then

{'time t3 minutes': [0, 0, 0, 1], 'time t2 minutes': [0, 0, 0, 1], 'bucket': [0, 1, 1, 1], 'minutes': [0, 0, 1, 1], 'water': [65, 15, 80, 129], 't3': [0, 0, 0, 1], 't2': [0, 0, 0, 1], 't1': [0, 0, 0, 2], 'tj': [0, 0, 0, 1]}

The correct answer is option 3.

This means that the time it took for the temperature to decrease from 75°C to 70°C, denoted as T, is greater than the time it took for the temperature to decrease from 70°C to 65°C, denoted as T2, and T2 is greater than the time it took for the temperature to decrease from 65°C to 60°C, denoted as T3.

Option 1 is incorrect because it states that Tx, T2, and Ts are equal, which contradicts the information given in the question.

Option 2 is incorrect because it states that T1 is less than T2, which is not supported by the information given in the question.

Option 4 is incorrect because it states that Tj is less than T3, which is also not supported by the information given in the question.

Therefore, the correct answer is option 3, as it correctly orders the times T, T2, and T3 in decreasing order.
