Answer 1

Given:

A is twice efficient than B.

A can work only for 8 hours a day while B can work for 12 hours a day

Formula used:

Men × Day = Total work

Calculation:

Let the time taken by B to complete work be b.

⇒ 2 × 8 × 12 = 1 × b × 12

⇒ b = 192/12

⇒ b = 16

∴ In 16 days, B alone can complete the work.
