A forms a wall in 10 days and B forms it in 15 days. A and B start the work of forming wall together but after 2 days A leaves the work. How many days are required for making the remaining wall by B?
Another 10 days. . Per day A does 1/10 of the wall and B 1/15 of the wall. After the 2nd day 2*1/10 + 2*1/15 = 5/15 of the wall has been completed. B needs another 10 days to finish the wall.
One Day work of both (A+B)=1/10+1/15 =5/30 =1/6 Two Days work of (A+B)=2/6 =1/3 Reamaining work=2/3 Time taken by B to complete the remaining work-2*15/3 =10 Days
P is able to do a piece of work in 15 days and Q can do the same work in 10 days. If they can work together for 2 days, what is the fraction of work left?
B is more efficient than A and they together can complete a work in 18 days. Had A done 60% of the work and then B, the remaining work, then the work would have been completed in 39 days. B alone will complete 60% of the same work in how many days?
B alone can complete the work in 45 days. A is 35% more efficient than B. If A and B together started the work but after 18 days A and B left. Then C alone completed the remaining work in 3 days. If they get Rs. 9750 as wages for the whole work, then what is the share of C in wages for the remaining work?
A, B and C together can complete a certain work in 24 days. A and C together work twice as much as B while A and B together works four times the as much as C, then A alone can do the same work in how many days?
