Answers and Solutions for Tables with Missing Values for CAT:

Solutions:

1) Answer (B)

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.

2) Answer (E)

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.

3) Answer (A)

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.

4) Answer (C)

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.
