Q12

Single Choice

What will be the result of the following Oracle SQL expression?

SQL Code

SELECT 10 - 4 FROM dual;

6 14 104

The subtraction operation 10 - 4 results in 6

Q13

Single Choice

Which Oracle SQL statement correctly calculates the product of two numbers, 7 and 3?

SELECT 7 + 3 FROM dual; SELECT 7 / 3 FROM dual; SELECT 7 * 3 FROM dual;SELECT 7 - 3 FROM dual;

The * operator is used for multiplication in Oracle SQL, so the correct expression is 7 * 3.

Q14

* % MOD/

The MOD function is used to find the remainder of a division operation in Oracle SQL.

Q16

Single Choice

Given the Oracle SQL query:What will be the result?

2.5 10 301.5

The division is performed first (15 / 3 = 5), followed by multiplication (5 * 2 = 10).

Q17

Single Choice

What will be the result of the following Oracle SQL expression?

SQL Code

SELECT 20 * (3 + 2) - 10 / 2 FROM dual;

90 80 4550

First, the addition within the parentheses is performed (3 + 2 = 5), then multiplication (20 * 5 = 100), and finally subtraction after division (100 - 10 / 2 = 100 - 5 = 95).

Q18

Single Choice

Consider this Oracle SQL query:What does the query calculate?

SQL Code

SELECT (salary * 12) + bonus - (tax / 2) AS annual_income
FROM employees;

Monthly income Annual income after tax deduction Annual income before tax deductionTotal income without considering tax

The query multiplies the salary by 12, adds the bonus, and subtracts half of the tax amount to calculate the annual income after partial tax deduction.

Q19

Single Choice

Single Choice

What is the result of the following Oracle SQL expression?

SQL Code

SELECT (25 + 10) * 2 - 50 / (5 - 3) FROM dual;

40 70 2550

The expression is evaluated as follows: (25 + 10) = 35, 35 * 2 = 70, and 50 / (5 - 3) = 25, then 70 - 25 = 45.
