A. 690

B. 674

C. 672

D. 960

Answer: Option C

### Solution(By Examveda Team)

Total employees = 1600
Female employees, 60% of 1600
$$= \frac{{60 \times 1600}}{{100}} = 960$$
Then male employees = 640
50% of male are computer literate,
= 320 male computer literate
62% of total employees are computer literate,
$$= \frac{{62 \times 1600}}{{100}} = 992$$     computer literate
Thus, Female computer literate = 992 - 320 = 672

Alternatively :
Let 60% employees are female and 40% are male
Then, 20% of male are computer literate and 42% are female computer literate
Female computer literate $$= \frac{{1600 \times 42}}{{100}} = 672$$
