8 1 % 3 - 11%
Correct Option: B
Number of officers = p.
Number of remaining employees = q.
According to the question,
8840 (p + q) = 15000p + 8000q
⇒ 8840p + 8840q = 15000p + 8000q
⇒ 15000p – 8840p = 8840q – 8000q
⇒ 6160p = 840q
| ⇒ | = | |||
| q | 6160 |
| = | = | |||
| 616 | 22 |
| ∴ Required percent = | × 100 = 12% | 25 |
