Statement 1
(1) Boogle had total 45,000 employees.
We know from the premise at 1/4th of senior software engineers were fired. However, we don't know how many SSEs were present in Boogle.
Hence this statement is not sufficient.
Statement 2
Before firing, out of all employees, 35% of the employees were senior software engineers..
Let the number of employees before firing = x
SSEs (Before Firing) = \(0.35 * x\)
SSEs(After Firing) = \(\frac{3}{4} * 0.35x = 0.75 * 0.35 * x\)
Percentage of employees are senior software engineers and still working at Boogle = \(\frac{0.75 * 0.35 * x }{ x} \) * 100
We can find the percentage.
Sufficient.
