**Calculation:**

A's 1 day's work = 1/10

Let B's 1 day's work be 1/b.

Ratio of their work done = 1/10 : 1/b

Ratio of their wages = 1/10 : 1/b

Total wages of work = 288 + 192 = Rs. 480

⇒ 288 = (1/10)/(1/10 + 1/b) × 480

⇒ (1/10 + 1/b) = 1/6

⇒ 1/b = 1/6 - 1/10

⇒ 1/b = 1/15

B alone can complete the work in 15 days.

**∴ Required difference = 15 - 10 = 5 days**

__Important Points__

Ratio of work done = Ratio of their wages
