Time & Work Questions – Part 2 – Maths & Reasoning

Q1. A is twice as good as B, and they work together in 20 days. So how long A alone will complete that task.
(a)40 (b)35 (c)30 (d)25
Q2. A is 2.5 times as good as B,B alone can do job in 35 days, So how long A and B together will complete that task
Q3. P can do one task in 9 days. Q is 50 percent more efficient than P,in how many days Q alone complete that task
(a)6 (b)3 (c)27/2 (d)5
Q4. A is 30 percent more efficient than B, A alone can do job in 23 days, So how longA and B together will complete that task
(a)11 (b)13 (c)20 (d)21
Q5. A and B together can do a work in 30 days. if After working for 23 days, B leave the work and total work is finished in 33 day. In how many days could B alone do the work?
Q6. A and B together can do a work in 27 days. if After working for 25 days, B leave the work and total work is finished in 30 day. In how many days could B alone do the work?
Q7. A and B can doa work in 30 days. He worked 10 days and after that with the help of C work will end the work in the next 10 days. If B’s 3 days work is equal to C 2 days work. In how many days A alone will complete the entire work
Q8. A and b together can do double the work than C,Where as B and C together can do thrice the work than A. If together they can finish a piece of work in 12 days. How much time will they individually take to finish the work?
Q9. 4 Man can do some work in 6 days while 3 womens can do the same work in 16 days. Find out that 1 man, 2 people together will do the same work in how long

Q10. 2 man can complete a work in 3 days, while 3 womens can complete the same work 4 days and 4 children complete the same work in 6 days. find in how much days 1 man and 2 child will complete the same work.

Q12. If 10 men or 20 women or 40 children can do one work within 7 months, how can 5 men, 5 women and 5 children together do half of that work?
Q13. A and B+C they spend equal time in doing a work. It A+B work within 10 days, but C alone does that work in 15 days, so B alone do the same work in?
Q14. two workers A and B working together can complete a job in 5 days .if A work twice as efficiently as he actually did and B work 1/3 efficiently as he actually did. then the work would have completed in 3 days . A alone can complete the work in how many days
Q15. A+B can complete a work in 8 days but if A and B work twice and 1 3 of their respective efficiency then the work is completed in 6 days in how many days A alone can comlete the work.

Q16. A+B can comlete a work in 6 days , in how many days they alone do the same work if A+C can complte the same work in 2 1/ 2 days lesser than B+C . they together complete the work in 5 days.
Q17. 6m + 8w do some work in 10 days while 26m + 48w does the same work in 2 days. find in how many days 7m + 6w will do that work.
Q18. A done 7/10 of work in15 days and completes the remaining work in 4 days with the help of B. find in how many days A+B together can complete that task.
