e.So 1/3 rd of the work = 18/3 = 6 minutes ANSWER-Thats really not the point. Machinery put a lot of men out of work,in England by Luddites -- textile workers who smashed the new mechanical looms.But you couldnt stop something that was so beneficial -- despite all the problems.Same thing these days with computerization.......
A machine can cut some piece of work in 6 minutes and a man using a hand saw could do it in 18 minutes. After 4 minutes there is a power shortage and the wood must be cut by hand saw. How many minutes must the man work to complete the task?

Machine can cut some piece of work in 6 minutes

So in 4 minutes , machine has done 4/6 of the job i.e. 2/3 rd

Remaining work = 1/3 rd

Man can complete the work in 18 minutes

So 1/3 rd of the work = 18/3 = 6 minutes ANSWER

That's really not the point. Machinery put a lot of men out of work, and there was a rebellion
in England by "Luddites" -- textile workers who smashed the new mechanical looms.
But you couldn't stop something that was so beneficial -- despite all the problems.
Same thing these days with computerization.

The man doesn't need to work. The man needs to have a cup of coffee and a cigarette and wait for the power to come back on.

well the machine got 2 thirds of the way through so the man has to do the other 3rd (at his pace) which is 18mins divided by 3

so the answer is 6 mins

(1 - 4/6) * 18 = 6 minutes
