INTRODUCTION TO TIME AND WORK:
There will be 1 or 2 Questions from this topic in all IBPS Exams.This topic is quite easy,Since Time and Work can be solved in Partial Method in our article we use LCM method to solve the problem in order to reduce the time consumption.There are 8 Basic types in Time and Work.Let us discuss each type with an example.
Before getting into the types let us see 3 important terms associated with Time and Work,
1st Term:Work = The total work which has to be completed
Example:It is not just the work,it may be eating ice creams,completing assignment it may be any work.
If Total Work is not given question then Total Work is LCM of Given numbers
2nd Term:Time=The time taken to complete the work it may be in Hours,Minute, Days,Months and Years
3rd Term Efficiency=Total Work/Time
Efficiency is nothing but Per day Capacity of the individual
Let us look each type with example:
PROBLEM BASED ON FINDING TOGETHER WORK:
In this type,we will be given the individual Capacity and we are asked to find the total working capacity.
1)A can complete the 15 days while B can do the same work in 30 days.Find in how many days they will take to complete the work if they work together?
#. 2.TYPE 2:
PROBLEMS BASED ON FINDING INDIVIDUAL WORK:
In this type we will be given together working capacity and one of their individual working capacity.
1)A works alone and complete the work in 12 days and when A and B work together they complete the work in 8 days then find in how many days B alone completes the work?
PROBLEMS BASED ON PARTIAL WORK:
This is again sub divided into 2 types:
1)Somebody will leave the group
2)Somebody will join the group
1)Somebody leave the group:
In this type,initially the people works together and after some day one of the them will leave the group.
1)A can Complete the total work in 25 days and B can Complete the total work in 15 days,Initially they both work together and After 5 days A Left,Find in how many days B alone take to complete the remaining work?
2)Someone Joins the group:
1)A can complete the work in 4 days and B can complete the work in 5 days.With the help of C,when A,B and C works together they can complete the work in 2 days.Find in how many days C alone Complete the work?
