Explanation:

Total employees in HR
= 16% of total employees = 16/100 × 2500 = 400.
employees in HR
= 5/8 × 400 = 250
Female employees in HR = 400 – 250 = 150.
Similarly,
Total employees in Marketing
= 15% of total employees
= 15/100 × 2500 = 375
Male employees in Marketing
=7/15 × 375 = 175.
Female employees in Marketing = 375 – 175 = 200.
∴ Required ratio = (250 + 175) : (150 + 200)
⇒ 425 : 350 ⇒ 17 : 14.
