Answer 1

Given:

A is twice as efficient as B and together they can finish a work in 24 days.

Formula used:

Men × Day = Total work

Calculation:

According to the question,

A = 2B

⇒ A/B = 2/1

⇒ Total work = (2 + 1)× 24

⇒ 72

B alone can finish the work

⇒ 72/1

⇒ 72 days

∴ B alone can finish the work in 72 days.
