Data Sufficiency

Last year an employee received a gross annual salary of $18,000, which has paid in equal paychecks throughout the year. What was the gross salary received in each of the paychecks?

1. The employee received a total of 24 paychecks during the year.
2. The employee received a paycheck twice a month each month during the year.

The OA is D.

Please, can someone assist me with this DS question? Thanks in advance!

Let the number of paychecks be 'n'
So, Per paycheck payment= 18000/n
Statement 1: It is sufficient as it gives the value of n=24
Statement 2: It is also sufficient, as we get, n=2*12= 24

Gross annual salary = $18, 000
Question : What was the gross salary received in each of the paychecks?

Statement 1: The employees received a total of 24 paychecks during the year.
$$therefore,gross salary per paycheck=\frac{\left[\$18,000\right]}{24}$$
= $750
Statement 2 is also sufficient.
Final answer is option D, because each statement alone is sufficient.
