Question

A is thrice as goos as workman B and together they finished the work in 15 days . In how many days will A alone finish the work ?

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
