Solution

Let H1, H2, H3 and H4 be the husbands and W1, W2, W3 and W4 be their wives respectively. The number of ways in which H1, H2, H3 and H4 can sit at the table is (4 – 1)! = 3! = 6.
Only two arrangements are possible for each of the above 6 cases (as illustrated by the figure given below for one of the cases):

So the answer = 2 × 6 = 12

If X is defined as the ratio of the total number of girls to the total number of students, then X was maximum in the year

2010-11

2013-14

2011-12

2012-13

Solution

Year	Students	Girls	Boys
2009-10	100	25	100-25 = 75
2010-11	200	50	150
2011-12	400	100	300
2012-13	450	250	200
2012-14	1000	450	550

X was maximum in the year 2012-13.The value of X was 250/450 = 5/9
For other years X is less than the above mentioned value.

Question 7

1 / -0

With reference to X as defined in previous question , it can be concluded that

The value of X did not increase during the period from 2009-10 to 2013-14

The value of X did not decrease during the period from 2009-10 to 2013-14

X remained constant during the period from 2009-10 to 2013-14

None of the above

Solution

Year	Students	Girls	Boys
2009-10	100	25	100-25 = 75
2010-11	200	50	150
2011-12	400	100	300
2012-13	450	250	200
2012-14	1000	450	550

Year	Students	Girls	x
2009-10	100	25	25/100 = 0.25
2010-11	200	50	0.25
2011-12	400	100	0.25
2012-13	450	250	0.56
2012-14	1000	450	0.45

It is evident, that X remained constant for first 3 years, then there is an increase followed by a decrease.
