Option 3 : 50/3

**Given:**

10 men working 4 hours per day can do a work = 15 days

**Concept:**

Work = Time × Efficiency

**Calculation:**

Let be assume the remaining work will be done in X days

⇒ (10 Men × 15 Days × 4 Hours) = (5 Days × 10 Men × 4 Hours) + (X Days × 6 Men × 4 Hours)

⇒ 600 = 200 + 24X

⇒ X = (600 - 200)/24 = 400/24 = 50/3

**∴ The required result will be 50/3.**
