A can do a piece of work in 60days while B can do it in 75 days they began together but 20 days before the completion of work A leaves off.how many days B takes to finish the remaining work?
Work done in last 20 days by A= W/3
................ Do............ by B= 4W/15
Total = 3W/5 to be done by B alone in 3/5 of 75= 45days
20 days before the completion of work A leaves means last 20 days me hi B work finish karega na!!
naah.. saket! 20 days dono milke karenge toh work cmplete hone wala hota he. but A wont work
so B will finish that work in how many days?? qsn aisa he
I too got the same ans. saket.
20days BEFORE COMPLETION likha h it mns last 20 days B wrkd alone nd Remaining work jo 220 aa ra h uska olmst 24(4/9) aa ra h..........to agr remaining work k liye puch ra h tv nsr to 24(4/9) hona chahiye na
jb total wrkng days of B puchega tb wo approx 45 aayega na.....!!!!
total work 300 total efficiency 5+4=9 efficiency of a is 5 so,a's work in 20 days is 5*20=100 then 400/9 that is 44 4/9
It is given, "they began together but 20 days before completion of work A leaves off" this doesn't mean both worked for 20 days or A alone worked for 20 days...
yes its 45 na almost
30 ya 20 nahi he na
sorry,i got wrong ans before u r right
arre bas mujhe yeh jaan na tha k mera sahi he? ya fir kuch aur he answer.. bas..
