Answer: Option A

Solution(By Examveda Team)

Given,
60% of work whose age is 30 above
1350 males work whose age is 30 above.
75% of workers are male whose age are 30 above.
25% of female workers whose ages are 30 above.
Number of female work whoes age 30 above
= $$\frac{{1350}}{{75}} \times 25 = 450$$
total number of work whoes age are 30 above = 1350 + 450 = 1800(60% of the work)
Total number of work = $$\frac{{1800}}{{60}} \times 100 = 3000$$
