SNAP 2009 Question Paper

The commission amount will be :
15,000 (12.5/100) 
= 15,000(25/200)
= Rs 1875

We have :
$$\sqrt{\ \frac{11025}{100}}\times\ \sqrt{\ \frac{1}{100}}\ \ \div\sqrt{\ 0.0025}-\sqrt{\ 420.25}$$
we will use BODMAS
and so we get $$10.5\times\ \frac{0.1}{0.05}-\sqrt{\ \frac{42025}{100}}$$
= 21-20.5
= 0.5

Total number of respondents under 31 = 66 
Total number of persons who liked blue = 3+2 =5
So in percentage we get (5/66 )(100) = 7.6

Total respondents in 21-30 =33
Respondents liking Rock = 12
So respondents liking other = 33-12 =21
Therefore in percentage : (21/33)*100 = 64%

Total number of people liking Jazz = 16
Total sample = 68+66 =134
So percentage = (16/134)(100) =12%

Total students in Arts faculty = 1049
Total non US students in arts faculty = 79+21+6+2+4 = 112
Now in percentage
We get :$$\frac{112}{1049}\times\ 100$$= 11%

Let the total number of students be x
Now it is given that 1049 students are in arts which is 23%
so we can say
x(23/100) = 1049
We get x =4560
Now Engineering faculty = 9% 
so we get number = (0.09)(4560) = 410

Let the total number of students be x
Now it is given that 1049 students are in arts which is 23%
so we can say
x(23/100) = 1049
We get x =4560

Let the total number of students be x
Now it is given that 1049 students are in arts which is 23%
so we can say
x(23/100) = 1049
We get x =4560
Now students studying science will be 4560(21/100) = 957
Now Asian students are studying Science will be 6% of total science 
= 0.06(957) 
= 57

Let the total number of students be x 
Now it is given that 1049 students are in arts which is 23%
so we can say 
x(23/100) = 1049
We get x =4560 
Now we know that medical students = 5% 
So number of medical students : 4560(0.05) = 228 students 
Now out of this 34 students are European 
So percentage of these with respect to total = $$\frac{34}{228}\times\ 100\ =\ 15\%$$
