Regular practice is essential to master Time and Work questions for the SBI PO exam. Attempt the SBI PO Time and Work Mostly Asked Questions Quiz below to assess your understanding of work efficiency, combined work, wages, and work completion concepts. Solving these questions will help you improve your calculation speed and accuracy while preparing for the examination.
Q1. A can complete a work in 25 days and B can do the same work in 20 days. They started working together, but A leaves after 5 days. How many total days did B work?
Efficiency of A = 100/25 = 4 units/day. Efficiency of B = 100/20 = 5 units/day.
Together they do (4+5) = 9 units/day. In 5 days, they complete 9 x 5 = 45 units.
Remaining work = 100 – 45 = 55 units.
B does the remaining work alone in 55 / 5 = 11 days.
Total days B worked = 5 (with A) + 11 (alone) = 16 days.
Q2. 15 men can complete a project in 20 days. In how many days can 20 men complete the same project?
15 x 20 = 20 x D2
300 = 20 x D2
D2 = 300 / 20 = 15 days.
Q3. A is 40 percent more efficient than B. If B takes 21 days to complete a work, how many days will A take to do the same work?
Time taken is inversely proportional to efficiency. So Time Ratio of A:B = 5:7.
If B takes 7 parts = 21 days (so 1 part = 3 days).
A will take 5 parts = 5 x 3 = 15 days.
Q4. A can do a work in 10 days and B can do it in 15 days. They work on alternate days starting with A. In how many days will the work be completed?
Efficiency of A = 3, Efficiency of B = 2.
They work alternately: Day 1 (A does 3), Day 2 (B does 2).
In a 2-day cycle, work done = 5 units.
To complete 30 units, they need 30/5 = 6 cycles.
Total days = 6 cycles x 2 days/cycle = 12 days.
Q5. A and B together can complete a work in 8 days. If B alone can complete the work in 12 days, in how many days can A alone complete it?
Efficiency of (A+B) = 24/8 = 3 units/day.
Efficiency of B = 24/12 = 2 units/day.
Efficiency of A = (A+B) – B = 3 – 2 = 1 unit/day.
Time for A alone = Total Work / A’s efficiency = 24 / 1 = 24 days.
Q6. A takes twice as much time as B and thrice as much time as C to complete a piece of work. Working together, they can finish it in 2 days. In how many days can B alone complete the work?
Efficiency is inverse to time. Efficiency ratio A:B:C = 1/6x : 1/3x : 1/2x = 1 : 2 : 3.
Total efficiency = 1 + 2 + 3 = 6 units/day.
They finish in 2 days, so Total Work = 6 x 2 = 12 units.
B’s efficiency is 2 units/day. Time for B = 12 / 2 = 6 days.
Q7. A, B, and C can complete a work in 10, 20, and 30 days respectively. If they all work together, how many days will they take?
Efficiencies: A = 6, B = 3, C = 2.
Total efficiency (A+B+C) = 6 + 3 + 2 = 11 units/day.
Time taken together = 60 / 11 = 5.45 days.
Q8. 5 men finish a piece of work in 6 days while 10 women finish it in 5 days. In how many days can 5 women and 3 men together finish the same work?
10 Women x 5 days = 50 Woman-days. (1 Woman takes 50 days).
Total Work = LCM(30, 50) = 150 units.
Efficiency of 1 Man = 5. Efficiency of 1 Woman = 3.
Efficiency of (5 Women + 3 Men) = (5 x 3) + (3 x 5) = 15 + 15 = 30 units/day.
Time taken = 150 / 30 = 5 days.
Q9. A completes half of a piece of work in 5 days. B completes one-third of the same work in 5 days. If they work together, in how many days will the work be completed?
If B does 1/3 work in 5 days, B can do full work in 15 days.
Total work = LCM(10, 15) = 30 units.
Efficiency of A = 3, Efficiency of B = 2. Together = 5 units/day.
Time taken together = 30 / 5 = 6 days.
Q10. A takes 30 days to finish a task and B takes 40 days to finish it. They work together for 12 days, then A leaves. In how many days will B finish the remaining work?
Efficiency of A = 4, Efficiency of B = 3.
Together their efficiency = 7 units/day.
Work done in 12 days = 12 x 7 = 84 units.
Remaining work = 120 – 84 = 36 units.
B finishes remaining work alone in 36 / 3 = 12 days.
