Question

A is twice as good as workman B. A and B can complete a eork in 14 days. A alone can complete a work in how many days?​

Answer 1

Answer:

Step-by-step explanation:

Let B be x and A be 2x

(A+B)'s 18 days' work=1

(A+B)'s 1 days' work=1/18

This can also be written as

x+2x=1/18

3x=1/18

x=1/54

Let's multiply both sides of this equation by 2.

Therefore,  

2x=1/27=>A's 1 day's work=1/27

Thus, A alone can do a piece of work in 27 days.
