Q.From the following data, compute the labour turnover rate under the

First find the average number of workers, then apply each method's formula; separations, replacements and their sum are the three numerators.

Step 1 — Average Number of Workers:

Average = (Workers at beginning + Workers at end) ÷ 2 = (190 + 210) ÷ 2 = 200.

Step 2 — Identify the figures:

• Separations (workers who left) = 20
• Replacements (new workers engaged to replace those who left) = 20
• (The 20 workers engaged for EXPANSION are NOT replacements — they are additions, so they are excluded from the replacement figure.)

Step 3 — Apply each formula:

1. Separation Method = (Separations ÷ Average Workers) × 100 = (20 ÷ 200) × 100 = 10%
2. Replacement Method = (Replacements ÷ Average Workers) × 100 = (20 ÷ 200) × 100 = 10%
3. Flux Method = ((Separations + Replacements) ÷ Average Workers) × 100 = ((20 + 20) ÷ 200) × 100 = (40 ÷ 200) × 100 = 20% …

Verification: the Flux rate should equal Separation rate + Replacement rate when computed this way: 10% + 10% = 20% — which matches the direct Flux …

The key trap is treating all 40 new workers as 'replacements' — only the 20 engaged to replace those who LEFT are replacements; the 20 engaged for EXPANSION are additions, not replacements. Also remember to use the …
