Important Formule
Work from Days:
If A can do a piece of work in n days, then A's 1 day's work = | 1 | . |
n |
Days from Work:
If A's 1 day's work = | 1 | , | then A can finish the work in n days. |
n |
Ratio:
If A is thrice as good a workman as B, then:
Ratio of work done by A and B = 3 : 1.
Ratio of times taken by A and B to finish a work = 1 : 3.
A and B can do a piece of work in ‘a’ days and ‘b’ days respectively.
When working together they will take a+bab days to finish the work
In one day, they will finish (aba+b)th part of work.
Efficiency is inversely proportional to the
Time taken when the amount
of work done is constant.
Efficiency is inversely proportional to the
Time taken when the amount of work done is constant.
Efficiency α = Time Taken1
Rule 6: Work of one day = Total number of working daysTotal work
Total work = one day work × Total number of working days
Remaining work = 1 – work done
Work done by A = A’s one day work × Total number of working days of A
Rule 7:If A can finish nm part of the work in D days.
Then total time taken to finish the work by A = nmD = mn × D days
Rule 8:
If A can do a work in ‘x’ days
B can do the same work in ‘y’ days
When they started working together, B left the work ‘m’ days before completion then total time taken to complete the work = (y+m)x/(x+y)
Rule 9: A and B finish work in a days.
They work together for ‘b days and then A or B left the work.
B or A finished the rest of the work in ‘d’ days.
Total time taken by A or B alone to complete the work = a–bad or a−bbd
In all the above formula,
M = Number of workers
D = Number of days
T = Time required
W = Units of work
E = Efficiency of worker
1. Question: A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs.3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?
Solution:
Let the total amount of work to be done be W units.
Productivity of A, Pa = W/6 units per day.
Productivity of B, Pb = W/8 units per day.
3 days x [Pa + Pb + Pc] = W => Pc = W/24 units per day
Ratio of wages of A: B: C = Ratios of their productivities = (W/6): (W/8): (W/24) = 4: 3: 1.
Amount to be paid to C = Rs.3200 x (1/8) = Rs.400
2. Question: It takes 6 hours for pump A, used alone, to fill a tank of water. Pump B used alone takes 8 hours to fill the same tank. We want to use three pumps: A, B and another pump C to fill the tank in 2 hours. What should be the rate of pump C? How long would it take pump C, used alone, to fill the tank?
Solution:
Let the total capacity of the tank be C liters.
Fill rate of pump A, Fa = C/6 liters per hr
Fill rate of pump B, Fb = C/8 liters per hr
2 hrs x [Fa + Fb + Fc] = C => Fc = 5C/24 liters per hr
Let‘t’ be the time taken by only pump C to fill the tank.
‘t’ hrs x 5C/24 = C => t = 24/5 = 4.8 hrs
