Answer 1

Given  : The Government has surveyed 100 people to find whether they are beneficial with the schemes introduced in recent

days. The summarized information regarding the usage of government schemes (number of people used) in 3

months given below:

Only August: 18;

August but not July: 23;

August and June: 8;

August: 28;

June: 48;

June and July: 10;

None of the three months: 24.  

To Find :  number of surveyed people who have used the schemes exactly two consecutive schemes (out of the three)

Solution:

only August  = 18

August but not July: 23

=> August  and June but  not July  = 23 - 18 = 5

August and June: 8;  

=>  All 3 months  =  8 - 5 = 3

June and July: 10;

All 3 months = 3

=> June and July  but not August = 10 - 3 = 7

August: 28;

July + august  but not June  = 28 - 18 -  8  =  2

number of surveyed people who have used the schemes exactly two consecutive schemes

June + July but  not august    and  July + august  but not June

=  7 + 2

=  9

9  people  have used the schemes exactly two consecutive schemes (out of the three)
