To evaluate the given SQL statement, let's break it down step by step:
The statement is:
SELECT ROUND(45.953, -1), TRUNC(45.936, 2) FROM dual;
The ROUND function rounds a number to a specified number of decimal places. In this case, the number 45.953 is rounded to the nearest 10th place, which is 50.
The TRUNC function truncates a number to a specified number of decimal places. In this case, the number 45.936 is truncated to 2 decimal places, which is 45.93.
Therefore, the values displayed by the SQL statement are 50 and 45.93.
Let's go through each option to understand why it is correct or incorrect:
Option A) 46 and 45 - This option is incorrect because the ROUND function rounds 45.953 to 50, not 46.
Option B) 46 and 45.93 - This option is incorrect because the ROUND function rounds 45.953 to 50, not 46.
Option C) 50 and 45.93 - This option is correct because the ROUND function rounds 45.953 to 50, and the TRUNC function truncates 45.936 to 45.93.
Option D) 50 and 45.9 - This option is incorrect because the TRUNC function truncates 45.936 to 45.93, not 45.9.
The correct answer is Option C.
