Aptitude and Reasoning Questions

The passage only provides the information that students drink in school but seem to stop binging after they graduate. Option [A] is incorrect as there is no mention in the passage that students
are only males and that they graduate at thirty. Options [B] and [D] are incorrect because it is not mentioned so in the passage. Since the passage talks about student groups - 'fraternity and sorority members' - a logical extension would be that it is these groups that prod students to begin drinking and with the breaking of these groups, the habit is also broken. Hence, [C].

Clearly, defence is necessary for the safety of the country, which is of prime importance. So, argument I holds. Also, a country can concentrate on internal progress and development only when it is safe from external aggressions. So, argument II does not hold.

Here, x = 20 and y = - 20
Therefore, the net % change in value
=x + y + xy100 %
= 20 + -20 + 20 × -20100%  or  - 4%

Since the sign is negative, there is a decrease in value by 4%.

If Vijay gives 'x' marbles to Ajay then Vijay and Ajay would have V - x and A + x marbles.
V - x = A + x --- (1)
If Ajay gives 2x marbles to Vijay then Ajay and Vijay would have A - 2x and V + 2x marbles.
V + 2x - (A - 2x) = 30 => V - A + 4x = 30 --- (2)
From (1) we have V - A = 2x
Substituting V - A = 2x in (2)
6x = 30 => x = 5.

We know that I = PTR/100
=> P = 20250/4.5 = 4500
Now, new Interest at 5% = 4500x1x5/100 = 225
Now the additional amount = 225 - 202.5 = Rs. 22.5
