A Correct answer
Explanation

Total marks = 200 * 144 = 28800. Male marks = 140 * 150 = 21000. Female marks = 28800 - 21000 = 7800. Number of females = 200 - 140 = 60. Average female marks = 7800 / 60 = 130.

AI explanation

The total marks of all 200 employees is 200 times 144, which equals 28800, while the total marks for the 140 males is 140 times 150, which equals 21000. The total marks for the 60 female employees is the overall total minus the males' total, giving 7800. The average marks for the females is 7800 divided by 60, resulting in 130.
