(1) The average (arithmetic mean) age of UltraCorp employees is 32.8, while the average age of MegaTech employees is 27.2.
(2) If the merger goes through and all employees from both companies remain employed, the average (arithmetic mean) age of the MegaUltraTech employees will be 31.4.

(1) The average (arithmetic mean) age of UltraCorp employees is 32.8, while the average age of MegaTech employees is 27.2.
Insufficient,
We get to know nothing about numbers/sum of ages from just averages.
(2) If the merger goes through and all employees from both companies remain employed, the average (arithmetic mean) age of the MegaUltraTech employees will be 31.4.
Insufficient,
We get to know nothing about individual averages from the combined average after the merger.
Combining (1) and (2),
Sufficient, we can see that 31.4 is closer to 32.8 (UltraCorp) as compared to 27.2 (MegaTech), this will happen only if UltraCorp has higher weightage which means employees are more in UltraCorp.
Hence, (C) is the answer.

Interesting line of thought to use average age as a relating factor to identify who has the higher number of employees
