Find three machines that can be replaced with hook ups of (xx5) machines.

Find the single machine that will do the same job as the given hook -up a. a(xx2^(3)) machine followed by (xx2^(-2)) machine. b. a(xx2^(4)) machine followed by (xx(1/2)^(2)) machine. c. a(xx5^(99)) machine followed by a (5^(-100)) machine.

Can this machine be adopted in farm work.

X can do a piece of work in 6 days while Y can do the same work in 8 days. Find in how many days X and Y together can do the same work? The following are the steps involved in solving the above problem. Arrange them in sequential order. One day's work of X is 1/6 one day's work of Y is 1/8 X can do a piece of work in 6 days and Y can do the same work in 8 days. X and Y together can do the same work in 3(3)/(7) days. One day's work of X and Y=(7)/(24)

In a press, there are three types of printing machines, P, Q and R. Machine P can print 10,000 pages in 8 hours, machine Q can finish the same task in 10 hours and machine R can finish the same task in 15 hours. All the three machines start the work at 9 : 00 a. m. Machine P breaks down at 11 : 00 a.m. and machines Q and R finish the task. The approximate time of completion of the job is :
