1.	A can complete a given task in 24 days, while B istwice as efficient as he. A started on the work initially,and was joined by B after a few days. If the wholework was completed in 10 days, after how many days,from the time A started working, did B join A?
Answer» Answer: Step-by-step EXPLANATION: `A is twice as good as B. Let B=x,A=2x A and B can complete the work together in 20 days. So,(A+B)’s 20 days’ work=1 (A+B)’s 1 day’s work=1/20 So, x+2x=1/20 3x=1/20 x=1/60 2x=1/30 A’s ONE day’s work=1/30 A can complete the work alone in 30 days. PLZZ MARK ME THE BRAINLIEST.. :):)

Answer:

Step-by-step EXPLANATION:

`A is twice as good as B.

Let B=x,A=2x

A and B can complete the work together in 20 days.

So,(A+B)’s 20 days’ work=1

(A+B)’s 1 day’s work=1/20

So,

x+2x=1/20

3x=1/20

x=1/60

2x=1/30

A’s ONE day’s work=1/30

A can complete the work alone in 30 days.
