30% of 120 = 36, so m = 36. Remaining is 120 -36, i.e 84. Finance is twice the operations, f= 2x, op = x. So 84 = 2x + x. x = 28. So, f = 56. op = 28, m =36.
Now 28 is laid off, we'll go from last sentence to accomodate correctly.
Half as many from operations as from finance. i.e y from operations mean, 2y from finance.
Twice as many from marketing as from finance means, marketing lost 2*2y, ie. 4y. So totally 7y were laid off. So y = 4.
Finance = 56 - 2y = 48.
Operations = 28 - y = 24.

At the end of the year, a company had exactly 120 employees working in three departments: Marketing, Finance, and Operations, with each employee working in exactly one of the three departments.
• Exactly 30% of these employees were in the Marketing department.
• Of the remaining employees, the number in Finance was twice the number in Operations.
At the beginning of the next year, the company decided to lay off a total of 28 employees from these three departments, with twice as many laid off from Marketing as from Finance, and half as many from Operations as from Finance.
