Question

Anthony can do a piece of work 3¼ days, then work done by Anthony in 1 day is ?​

Answer 1

Answer:

Let, Anthony can do x amount of work in 1 hour, Bentley can do y amount of work in 1 hour and Caleb can do z amount of work in 1 hour.

So, 4x = 1……………………………(i)

And, 3y + 3z = 1…………………………(ii)

And, 2x + 2z = 1……………………………(iii)

From (i); x = (1 / 4).

Putting x = (1 / 4) in (iii), we get:

2z = (1 / 2)

z = (1 / 4).

Putting z = (1 / 4) in (ii), we get:

3y = 1 - (3 / 4) = (1 / 4)

y = (1 / 12).

So, Bentley needs (1 / y) = 12 hours to complete the job alone.
