For the following questions answer them individually

Question 61

There are 6 volumes of books on a rack kept in order (such as, vol. 1, vol. 2 and so on). After some readers used them, their order got disturbed. The changes showed as follows:
Vol.5 was directly to the right of vol. 2
Vol 4 has vol. 6 to its left and both were not at Vol.3's place.
Vol.1 has Vol.3 on right and Vol.5 on left.
An even numbered volume is at Vol.5's place.
Find the order in which the books are kept now, from the four given alternatives:

Video Solution

Solution

"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.

Question 62

All German philosophers, except for Marx, are idealists. From which of the following can the statements above be most properly inferred?

Video Solution

Solution

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.

Question 63

Ramaswami was studying for his examinations and the lights went off. It was around 1:00 a.m. He lighted two uniform candles of equal length but one thicker than the other. The thick candle is supposed to last six hours and the thin one two hours less. When he finally
went to sleep, the thick candle was twice as long as the thin one. For how long did Ramaswami study in candle light?

Video Solution

Solution

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

Question 64

The numerator and denominator of a fraction is in the ratio 2:3. If 6 are subtracted from the numerator the value of the fraction becomes $$\frac{2}{3}$$ of the original fraction. The numerator of the original fraction is,

Video Solution

Solution

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.

Question 65

A person wanted to withdraw X rupees and Y paise from the bank. But cashier made a mistake and gave him Y rupees and X paise. Neither the person nor the cashier noticed that. After spending 20 paise, the person counts the money. To his surprise, he has double the amount he wanted to withdraw.
Find X and Y. (1 Rupee = 100 Paise)

Video Solution

Solution

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.

Question 66

A drawer contains 10 black and 10 brown socks which are all mixed up. What is the fewest number of socks you can take from the drawer without looking and be sure to get a pair of the same color?

Video Solution

Solution

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.

Question 67

A placement company has to assign 1000 SW personnel who are skilled in Java and Dot Net to a prospective outsourcing company. He finds that 750 are having Dot Net skills and 450 have Java skills. Some have skills in both Java and Dot Net. Find the numbers who have skills in both Java and Dot Net.

Video Solution

Solution

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.

Question 68

All good athletes who want to win are disciplined and have a well balanced diet. Therefore, athletes who do not have well balanced diets are bad athletes. Based on the sentence above which of the statement below strongly supports the view :

Video Solution

Solution

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.

Question 69

The numbers in these series are arranged in a triangle which has a logic as shown. Find the missing numbers shown as (?) from the choices given below:

Video Solution

Solution

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.

Question 70

If for a particular value of the variable x, the following holds good, $$17 = \frac{17x}{(1 - x)}$$, then compute the value of (2x)*x.

Video Solution

Solution

Solving the eqn:

we get x = (1/2)

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