Answer 1

Step-by-step explanation:

Allen, Ben and Carl together take 60 hours to complete a certain amount of work, while Allen, Ben and David together take 72 hours Allen, Carl and David together take 84 hours and Ben, Carl and David together take 48 hours to complete the same amount of work. Who is the slowest worker?

Answer 2

Adam is the slowest worker of them all.

Given,

Adam, Ben, and Carl together take 60 hrs.

Adam, Ben, and David together take 72 hrs.

Adam, Carl, and David together take 84 hrs.

Ben, Carl, and David together take 48 hrs.

To Find,

Slowest worker

Solution,

Let's solve the question,

Adam, Ben, and Carl together take 60 hrs.

So, They alone take

3x = 60

x = 20 hrs per person

Adam, Ben, and David together take 72 hrs.

So, They alone take

3x = 72

x = 24 hrs per person

Adam, Carl, and David together take 84 hrs.

So, They alone take

3x = 84

x = 28 hrs per person

Ben, Carl, and David together take 48 hrs.

So, They alone take

3x = 48

x = 16 hrs per person

So, the total time is taken per person,

Adam = 20+24+28 = 72

Ben = 20+24+16 = 60

Carl = 20+28+16 = 64

David = 24+28+16 = 68.

Adam is the slowest worker of them all.
