What is the easiest way to solve time and work questions?
C – 20 days, 40 days. D – 10 days, 50 days. (A+B)’s 1 day work = 1/12, (B+C)’s 1 day work = 1/15, (C+A)’S 1 day work = 1/20 Including: 2(A+B+C)’s 1 day work = (1/12+ 1/15+ 1/20)= 12/60 = 1/5 ∴ (A+B+C) `s 1 day work = (1/2 *1/5) = 1/10 ∴ working together they can complete the work in 10 days.
How do you solve questions quickly?
3 tricks for solving problems faster and better
- Trade problems with someone. When you get stuck, stop hammering away at the problem and find a colleague to swap with.
- Solve problems on behalf of someone else.
- Put some distance between yourself and your project.
What is the equation for work time?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
What is MDH formula?
Man – Work – Hour Formula: Total effort or work = MT man hours. If A can do a piece of work in D days, then A’s 1 day’s work = 1/D.
How can I be intelligent in math?
How to Get Smarter in Math
- Learn Smarter. Just as people are either left- or right-handed, they also have dominant brain hemispheres.
- Study Smarter. Because math is a learned skill that requires practice, you may need to spend more time on homework and studying than you do in other subjects.
- Practice Smarter.
- Think Smarter.
What is the formula for work?
In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
What is the formula of speed distance and time?
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
What is the formula for time and work?
Thus, knowing the formula for any numerical ability topic make the solution and the related calculations simpler. Given below are a few such important time and work formulas for your reference: Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work.
How to solve the time and work problem?
An effective Time and work shortcut trick that will help you to solve the Time and Work problem is this Fraction conversion table. Try to directly remember fraction conversion into percentage. Check some examples given in the table below. For example, let us suppose that A can do a job in 10 days. A = 10 days i.e so work done in a day is 1/10 th.
What is the formula to calculate the amount of work done?
Time Taken = 1 / Rate of Work If a piece of work is done in x number of days, then the work done in one day = 1/x Total Wok Done = Number of Days × Efficiency Efficiency and Time are inversely proportional to each other
What is the formula that solves distance rate and time?
You will also apply the formula that solves distance, rate, and time, which is distance = rate x tim e. It is abbreviated as: There are many examples where you might use this formula in real life. For example, if you know the time and rate a person is traveling on a train, you can quickly calculate how far he traveled.
