The savings of the family for the year were equal to the expenditure on:

From above graph , we have
Expenditure on clothing = 10%
Expenditure on education of children = 12%
Expenditure on transport = 5%
? Total Expenditure = Expenditure on clothing + Expenditure on education of children + Expenditure on transport
Total Expenditure = 10% + 12% + 5% = 27%

From above given pie-chart ,
It is clear that Maximum expenditure of the family other than on food is on others .
Hence Required Answer will be on others ( 20% ) .

As per first graph,
The number of students in Collage A = Total number of students x 21%
The number of students in Collage A = 3500 x 21/100
The number of students in Collage A = 35 x 21 = 735
As per second graph,
The total number of girls from College A = Total number of girls x 23%
The total number of girls from College A = 1800 x 23/100
The total number of girls from College A = 18 x 23 = 414
Number of boys from college A = Total number of students in Collage A - The total number of girls from College A
Since, number of boys from college A = 735 - 414 = 321
Required percentage = 100 x Number of Boys from Collage A / Total number of boys in collage A
Required percentage = 100 x 321/735
Required percentage = 2140/49 = 43.67%

As per given graph, we can see that the % spending for following sports are same.
Tennis = 10 % and Others = 10 %.
Golf = 12.5 % and Basketball = 12.5 %
Football = 15% and Hockey = 15 %
The country spent the same amount of money on Golf and Basketball , which is 12.5% in each .
So , Answer will be Golf and Basketball .

From above given graph ,
It is clear that the most popular game is Cricket because the country is spent more amount of money on other game.
So Answer will be Cricket .

From above given graph ,
The total amount spent on football = 15 %
The total amount spent on Hockey = 15 %
Required ratio = The total amount spent on football : The total amount spent on Hockey
Required ratio = 15 : 15 = 1 : 1.
