Q. It would take one machine 4 hours to complete a production order and another machine 2 hours to complete the same order. If both machines work simultaneously at their respective constant rates, the time taken to complete the same order is_______________hours.<\/p>\n\n\n\n
(A) 2\/3<\/p>\n\n\n\n
(B) 3\/4<\/p>\n\n\n\n
(C) 4\/3<\/p>\n\n\n\n
(D) 7\/3<\/p>\n\n\n\n
Ans: 4\/3<\/p>\n\n\n\n
Solution: <\/p>\n\n\n\n
Machine X=4 hours<\/p>\n\n\n\n
Machine Y=2 hours<\/p>\n\n\n\n
In 1 hour X can work=1\/4<\/p>\n\n\n\n
In 1 hour Y can work=1\/2<\/p>\n\n\n\n
In 1 hour (X+Y) can work<\/p>\n\n\n\n
=1\/4+1\/2=3\/4<\/p>\n\n\n\n
(X+Y) together=4\/3 hours<\/p>\n","protected":false},"excerpt":{"rendered":"
