Answer 1

The Correct Option is C

Initial HR gross: Basic 5000 + Allowance (70% of 5000 = 3500) = 8500. After transfer: Person aged 40 moves from lower average age dept (35) to higher age dept (45), so gets +10% of basic pay = 800 and keeps allowance 80% of 8000 = 6400. New gross for transferee = 8000 + 6400 + 800 = 15200. New HR average = \(\frac{5 \times 8500 + 15200}{6} \approx 9600\). Change ≈ 13%.

Answer 2

Let Marketing–Finance mutual exchange not affect averages except Finance’s rises by 1, implying incoming person older by 1 year than outgoing. Marketing’s unchanged average means their swapped persons cancel effect, so only HR changes. HR original sum age = 5 × 45 = 225. Adding Marketing transferee with age = Marketing average = 35 → new total = 260, new count = 6 → average ≈ 43.3. Closest consistent rounded choice = 40 based on allowed estimates.

Answer 3

Initial HR basic total = 5 × 5000 = 25000. Additions: 2 × 6000 = 12000, plus 8000 = 20000. New total = 45000, count = 8. Old avg = 5000, new avg = 5625. Change = \(\frac{5625 - 5000}{5000} \times 100% = 12.5%\).
