Q:

There are 44 students in a hostel, due to the administration,  15 new students has joined. The expense of the mess increase by Rs. 33 per day. While the average expenditure per head diminished by Rs. 3, what was the original expenditure of the mess ?

A) Rs. 404 B) Rs. 514
C) Rs. 340 D) Rs. 616
 
Answer & Explanation Answer: D) Rs. 616

Explanation:

Let the average expenditure per head be Rs. p
Now, the expenditure of the mess for old students is Rs. 44p
After joining of 15 more students, the average expenditure per head is decreased by Rs. 3 => p-3
Here, given the expenditure of the mess for (44+15 = 59) students is increased by Rs. 33
Therefore, 59(p-3) = 44p + 33
59p - 177 = 44p + 33
15p = 210
=> p = 14
Thus, the expenditure of the mess for old students is Rs. 44p = 44 x 14 = Rs. 616.

Q:

Should there be a complete ban on import of sugar by India?

Arguments :

I. No. The production of sugar in India is not sufficient to meet the requirement.

II. No. This will keep the prices of sugar under control as the supply will be adequate.

A) If only argument I is strong B) If only argument II is strong
C) If neither I nor II is strong D) If both I and II are strong
 
Answer & Explanation Answer: D) If both I and II are strong

Explanation:

Import of sugar is directly related with the domestic production of sugar. If import of sugar is banned then it will result in hoarding of sugar besides increase in its prices (due to less supply than the requirement). Hence I is strong. Note that availability of a commodity keeps the prices of the commodity under control. Hence, II is strong.
