SNAP 2010 Question Paper

"Vol.5 was directly to the right of vol. 2" using this statement, we can eliminate options A, B and C.

Option D satisfies all of the given statements.

Option A & B imply that Marx is not German and is an idealist philosopher which is not the correct implication.

From option D we can infer that there can be other German philosophers who are not idealists like Marx. This is the same implication as stated in the question.

Option C implies the same as given in the question.

Assume that the initial lenght of both the candle was L and Vipul studied for X hours.
In X hours, total thick candle burnt = XL/6
In X hours, total thin candle burnt = XL/4
After X hours, total thick candle remaining = L - XL/6
After X hours, total thin candle remaining = L - XL/4
Also, it is given that the thick candle was twice as long as the thin one when he finally went to sleep.
(L - XL/6) = 2(L - XL/4)
(6 - X)/6 = (4 - X)/2
(6 - X) = 3*(4 - X)
6 - X = 12 - 3X
2X = 6
X = 3

Let the numerator be 2x and the denominator be 3x. On subtracting 6 from the numerator, we get the equation as:

On solving this, we get x = 9 and the numerator as 18.

Expressing the money he wanted to withdraw in terms of paise: 100x + y

Expressing the amount the cashier gave him: 100y + x

After spending 20paise from the withdrawn money, he finds he still has double the amt, he actually wished to withdraw.

So the eqn is: (100y+x) - 20 = 2(100x+y)

=> 98y - 199x = 20   ...(1)

Only option B satisfies eqn 1 among the given options.

For this, we have to consider the worst possible case.

Suppose we get a black piece in the 1st pick and then a brown one in the 2nd pick.

In the 3rd pick, we will either get a black one or a brown one and when it will be placed with the previous two pieces, we will definitely get a pair of socks of the same colour.

If 750 are skilled in Java, 250 are skilled only in DotNet. Of the 450 who are skilled in DotNet, we just found out that 250 are skilled only in DotNet, meaning that rest 200 out of the 450 are skilled in both.

Bad athletes do not have well-balanced diets. It doesn't;t mean they don't want to win. A can be ruled out.

good athletes have a well-balanced diet. It doesn't imply all those who eats a well-balanced diet are good.. C can be ruled out.

D hasn't been mentioned.

In the 3rd row, the second element i.e. 4 comes as the product of the 2's in the row above. Similarly, second element of the 4th row i.e. 8 comes as the product of the 2 and the 4 above it.

Using this pattern, the 3 '?' will be 8, 1024 and 32.

Solving the eqn:

we get x = (1/2)

So 2 x (1/2) x (1/2) = 1/2
