A Correct answer
Explanation

MOD(1600, 10) returns 0 (1600 is divisible by 10). TRUNC(0, -1) truncates to tens place = 0. ROUND(0, 2) rounds to 2 decimal places = 0. The final result is 0 as an integer, not 0.00 (which would be a formatted number). Option A is correct.

AI explanation

To evaluate the given SQL statement: SELECT ROUND (TRUNC (MOD (1600, 10),-1), 2) FROM dual;

Let's break it down step by step:

  1. MOD (1600, 10): This returns the remainder when 1600 is divided by 10. The result is 0.

  2. TRUNC (0, -1): This truncates the number 0 to the nearest 10th place. Since the decimal place is -1, it rounds down to the nearest 10th. The result is still 0.

  3. ROUND (0, 2): This rounds the number 0 to 2 decimal places. Since the number has no decimal places, it remains 0.

Therefore, the SQL statement will display 0 as the result.

The correct answer is A) 0.
