Note: When more people working on a similar type of work, then there group work = Sum of each person 1 day’s work.
Suppose P, Q, R work same piece of work by each person ( P + Q + R )”s 1 day’s work = P’s 1 day’s work + Q’s 1 day’s work + R’s 1 day’s work.
A and B alone can do a piece of wok in 8 and 18 days respectively. In how many days the work will be completed if they both work on alternate days starting with B?
A, B and C can all together do piece of work in 10 days, in which B takes three times as long as A and C together do the work and C takes twice as long as A and B together take to do the work. In how many days B can alone do the work?
20 men can complete a piece of work in 14 days. 7 men started the work and after 20 days, 7 more men joined the work. In how many days the remaining work will be completed?
