Verbal Reasoning

Modern warfare does not revolve around the usage of standard weapons and armaments only. Recently China held India hostage, when an artificial lake was formed in a region in Tibet under the control of the Chinese, and the overflow of the lake or a leakage in the dam could overflow the Sutlej and hence flood the entire Sutlej basin in India. China refused permission to Indian specialists to inspect the lake, and held the country ransom to a "water bomb". Again, the US is arm-twisting India to support US on major issues like Iraq and terrorism, in return for supporting India's demand for a UNSC seat. These are symptoms of war, albeit of a different kind.

Which of the following would qualify as war, according to the definition of war described above?

1.The refusal of the Taliban government in Afghanistan to permit Indian forces to free hostages by use of force, of an Indian plane hijacked in India and taken to Afghanistan.

2. The refusal of a groom to marry just before the marriage ritual if the bride's family did not provide him a Maruti 800 car in dowry

3. The US slapping high duties on Chinese exports to USA, in retaliation to rising trade deficit of USA with China, and the Chinese refusal to devalue its currency to set into order the imbalance in trade.

4. A strike called by farmers in the rest of Maharashtra to protest against the decision of the government to cut power in the rest of the state to provide uninterrupted power to the capital Mumbai, when the power was actually generated outside Mumbai.

Quantitative Ability



In the above figure,\angle BXC = x^\circ ,\angle BCX = y^\circ
Find \quad \angle DCY

(1) (x+y)^\circ
(2)(x-y)^\circ
(3)90^\circ - (x+y)^\circ
(4)180^\circ - (x+y)^\circ
(5)None

So,folks here are the correct answers

Verbal Reasoning
The correct answer is (3). The kind of 'war' being spoken here is blackmail, armtwisting etc. between nations. That is the underlying current in option 3, as when US failed to convice China to devalue its currency, it starts seeking other options, in trying to force China to do so.
Quantitative Ability
The correct answer is (1).
It is clear that
\angle CBD = (x+y)^\circ
Since the angle made by the chord with the tangent at the point of the contact and the angle made by it at any point on the alternate segment are equal (Alternate Segment Theorem),
\angle DCY = (x+y)^\circ

    Quant Q. : (X+y) Explanation – Angle DBC is external angle of the triangle XBC. Thus, angle DBC = Sum of two interior remote angles = (x+y) Now, applying alternate segment theorem, we get Angle DCY = angle DBC = (x+y) (Taking DC as chord and XY as tangent to circle)
