Shortcuts in solving aptitude-5

TIME AND WORK

Introduction:

In any business effort it is very important to be good as well as clever at calculating the number of people required to delegate to a piece of work so that the work can be completed in a stipulated time.  The following are some of the basic aspects related to TIME and WORK.
Work done is usually considered as one unit.  Time taken to do the work depends on various factors such as the number of Persons’ doing the work, their efficiency ‘in doing the work’, ‘amount of work they bear’, ‘number of days they take’ and time they spend per day. In case, there is more than one person carrying out the work, it is assumed that each person does the same amount of work each day.

Work and Wages

Introduction:

At Certain times people show little interest in calculating expenditure on petty things such as spending money for a servant maid or for the repair of a tank, pipe or a cistern. But this is a very serious issue for organizations to reduce their expenditure.  Hence they calculate as follows.
Wages earned by people by doing some work together are to be distributed in the ratio of the total work done by each of them.  If a group of people work at different places and if the work done by each of them per day is different then the wages of earnings have to be divided in the ratio of the work per day to each of them.
i.e., if ‘A’ can do a piece of work in ‘x’ days and ‘B’ in ‘y’ days, then the wages are to be distributed in the ratio of 1/x : 1/y, If three men can do a task in x,y and z days respectively then the wages are to be distributed in the ratio of 1/x:1/y:1/z.
