Choice B 9 hours Step-by-step rationalization: Given : Three machines working independently, concurrently, and on the identical fixed price can fill a sure manufacturing order in 36 hours. If one extra machine had been used beneath the identical working circumstances. To search out : In what number of fewer hours of simultaneous operation might the manufacturing order be stuffed Answer : Let the numbers of hours taken together with extra machine i.e. 4 machines be x hours. So, 3 machines take 36 hours and 4 machines take x hours. Then, i.e. 4 machines spend 27 hours to do work. Variety of fewer hours of simultaneous operation might the manufacturing order be stuffed is given by, hours Due to this fact, the work may very well be completed in 9 hours much less.

So, the proper reply is B.

D Step-by-step rationalization: Let the entire manufacturing order be X. The mixed price is thus x/36 orders per hour. Now, we all know that the three machines are working on the identical fixed price. Which means that particular person price for every of the machines can be x/36 divided by 3 and that offers x/108 per machine. Now, were having one other machine coming on the identical fixed price. This implies were including an x/108 price to the preexisting x/36. The brand new complete price thus turns into x/108 x/36 = 4x/108 Now we all know that the entire new price is 4x/108. For the reason that complete work doesnt change and its nonetheless x, the time taken to finish a piece of x orders at a price of 4x/108 order per hour can be x divided by 4x/108 and that is x * 108/4x = 108/4 = 27 hours
