Question:

The author’s main purpose behind writing the passage is

A

To explain why Van Dyck was a better artist than Rubens.

B

To praise the underappreciated works of Van Dyck.

C

To compare Van Dyck’s works with that of Rubens.

D

To explain why he prefers Van Dyck's art over Rubens'.

Doubt

I don't get how c is incorrect, in the third paragraph starting it is explicitly stated how comparison is made and even if we overlook the stated line, in the rc overall, a clean comparison is made between them. I don't know when to choose the ans that are explicitly stated or when to overuse brain to think which should be correct and acc to the RCS that come in CAT.

Question:

An escalator is moving down. A climbs down from this escalator by taking 20 steps. B climbs down from this escalator by taking 40 steps. When the escalator is stationary the ratio of the speed of A and B is 1:4. Find the number of visible steps on an escalator.

A

40

B

20

C

60

D

80

Doubt

Hi, since it is given that the escalator is moving downwards then why did we only consider the speed of the person while calculating the time? shouldnt we consider the relative velocity while calculating t??

Question:

The Geeta Ice factory supplies ice to the nearby Juice shops in trucks that travel at a rate of 50 km/hr. After every one hour of travel exactly one-fourth of the total ice gets melted. On a particular day, the factory received an order from a Juice shop which is 100 km away. The Ice factory decides to make sure to place an adequate amount of Ice before the transit to compensate for the melting process and charges for the end quantity. If the company decides to sell the ice at marked price what should be the mark-up percentage to make sure the company neither earns a profit nor a loss from the transaction?

A

55.55%

B

66.66%

C

77.77%

D

88.88%

Question:

The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.

Several of the world’s earliest cities were organised along egalitarian lines. In some regions, urban populations governed themselves for centuries without any indication of the temples and palaces that would later emerge; in others, temples and palaces never emerged at all, and there is simply no evidence of a class of administrators or any other sort of ruling stratum. It would seem that the mere fact of urban life does not, necessarily, imply any particular form of political organization, and never did. Far from resigning us to inequality, the picture that is now emerging of humanity’s past may open our eyes to egalitarian possibilities we otherwise would have never considered.

A

The lack of hierarchical administration in ancient cities can be deduced by the absence of religious and regal structures such as temples and palaces.

B

Contrary to our assumption that urban settlements have always involved hierarchical political and administrative structures, ancient cities were not organised in this way.

C

The emergence of a class of administrators and ruling stratum transformed the egalitarian urban life of ancient cities to the hierarchical civic organisations of today.

D

We now have the evidence in support of the existence of an egalitarian urban life in some ancient cities, where political and civic organisation was far less hierarchical.

Doubt

In the 5th question, for option B, if instead of ''all'' , ''some ancient cities'' is given, then will option B be correct

Doubt

The passage puts out arguments without any scientific research or historical evidence backing, then how can we say that we now have evidence about these structures.

Question:

Brass is an alloy which is formed by mixing copper and zinc in the ratio 2:1. Another alloy bronze is formed by mixing copper and tin in the ratio 3:4. An alloy nickel silver is formed by mixing the alloys brass and bronze in a certain ratio such that the ratio of zinc and tin in ‘nickel silver’ is 5:6. Which of the following correctly represents the share of copper in the alloy silver nickel?

A

$$\frac{29}{51}$$

B

$$\frac{37}{43}$$

C

$$\frac{23}{31}$$

D

$$\frac{27}{37}$$

Doubt

Shortcut: Multiply Brass(C:Z) with 5 and Bronze(C:T) with 1.5 which would make Zinc as 5 and Tin as 6 which is the Nickel Silver ratio given in question. So copper from both would add upto 14.5, so final ratio in Nickel Silver is 14.5:5:6(C:Z:T). So ratio of Copper in final mixture is 14.5/22.5 = 29/51(ans.)

D

198782

Doubt

Hi Team, Why can't the equation be
432320 = x(1.2)^3 + x (1.2)^2 + x (1.2) like by equating future value formula as explained in the video ?
