Answers and Solutions for Tables with Missing Values for CAT:

Solutions:

According to given condition No of male students in 11,12 and in total are 44 , 48 and 380.
So No of males in secondary are 380-44-48=288.
288 students => 45% of total secondary students.

There are 640 secondary section students, 80 11th class students and 80 12th class students.
If the fraction of vegetarians in 12th class is x, then
80x + 80*0.5 + 640*0.55 = 0.53*800
=> x + 0.5 + 4.4 = 5.3 => x = 0.4
=> There are 32 vegetarian students in class 12.
25% of class 12 i.e 8 are males.
So there are 24 vegetarian female students.
No. of non-veg males = 40 and veg females=24. Required answer 40 – 24 = 16.

There are 640 secondary section students, 80 11th class students and 80 12th class students.
If the fraction of vegetarians in 12th class is x, then
80x + 80*0.5 + 640*0.55 = 0.53*800
=> x + 0.5 + 4.4 = 5.3 => x = 0.4
=> 40% are vegetarians in class 12.

x is the fraction of male members in the secondary section.
0.6*80 + 0.55*80 + 640x = 800*0.475
=> 0.6 + 0.55 + 8x = 4.75
=> 8x = 3.6 => x = 0.45
=> 45% are males and 55% are females => 288 males and 352 females
=> There are 144 vegetarian males and 208 vegetarian females .
Also there are 144 non-vegetarian males and 144 non-vegetarian females.
So leaving vegetarian females all others are same in nos.
