CAT Practice Test: Week 5 - CAT MCQ

Average of low rates of shares of Reliance = (177.5+177.5+177) / 3> 177, which is the low rate of share of Reliance at Bangalore stock exchange. So, the correct option is 3.

Alternatively,
We know that, the city having the smallest value will be lesser than the average and the city having the largest value will be definitely more than the average. Using this logic, the answer can be marked as Bangalore.

 Low rate of share of L & T at Madras Stock Exchange = Rs. 180.

Total of low rate of share of L & T in all three Stock Exchanges = Rs. 500.
Ratio of (i)/(ii)= 180/500 = 9/25. Hence, the answer is D option.

The last column is the total of all three stock exchanges (high rates and low rates, resp.) for every company. So, the average for NEPC high rates = 85.25/3= Rs. 28.42. Hence, the answer is 1st option.

Alternatively,
We know that, average has to lie somewhere in between the two extreme values. Here, the values are 28, 28.25 and 29. The second and third options are out of this range and fourth option is too close to the higher end. Thus, the only option left is the first one and hence, that is the answer.

At Bangalore Stock Exchange, ratio of high rate to low rate = (160/143) = 1.11;
At Madras Stock Exchange, ratio of high rate to low rate = (158/140.5) = 1.12;
At Bombay Stock Exchange, ratio of high rate to low rate = (161.25/142.5) = 1.13.
As the maximum ratio is in Bombay, it will be the answer. Hence, the answer option is 3.

This one is very simple one.
Forex in 2006-07 = 5000
Forex in 2004-05 = 3000 (nearest value)
The answer is 5000/3000 = 1.66 or almost 1.6

Average forex reserve is 3480. Forex Reserve in 2005-06 = 4320.
Hence, percentage = [4320/ 3480]* 100 = 124.14% = 125%

In this case, we first need to find the average forex reserve and then find the ratio between the years when they are above the average and below the average.
Average Forex = (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) / 8 = 3480
Now, the years that are below the average = 2000-01, 2002-03, 2003-04, 2004-05, 2007-08
The years that are above the average = 2001-02, 2005-06, 2006-07
Hence, the ratio will be 3:5

In this question we need to use percentages,
First the years in which forex rose compared to previous year = 2001-02, 2003-04, 2005-06, 2006-07
Percentage increase in these years compared to last year, 2001-02 = (3720 – 2640)/ 2640 * 100 = 40.9090%
2003-04 = (3360 – 2520)/ 2520 *100 = 33.33%
2005-06 = (4320 – 3120)/ 3120* 100 = 37.88%
2006-07 = (5040 – 4320) / 4320* 100 = 16.67%
Hence, the ans. Is 2001-02

Total students = 170
No. of students who are in none category = 30
Therefore, percentage of students who have cleared at least one = [(170 – 30) / 170] x 100 = 82.35%

We need to calculate percentage of students who cleared CAT in 2000,
As shown above, there are 20 students who cleared CAT in 2000.
And, Total students are 170
Hence, 20/170 x 100 = 11.76%

The analogy is that 'beginning' and 'ending' denote the start and end of something. 'Beginning' refers to the point in time or space at which something begins. 'Ending' refers to the final or last part of something. Similarly, the 'preface' to a book comes at the start, while an 'afterword' is a 'literary device that is often found at the end of a piece of literature'. Thus, option B is correct.
(a) - 'Symphony' and 'movement' do not denote a start or an end.
(c) - Both 'introduction' and 'foreword' represent the beginning.
(d) - While 'prologue' denotes beginning, 'intermission' does not denote ending.

'Easy come, Easy go' is said when something, especially money, is easily got and then soon spent or lost.

The first is the main ingredient for making the second. 'Dough' is used to make bread. 'Words' are used in speech and they alone can make a speech.

The relation is one of a thing and its removal. The coming off of topsoil is called 'erosion'; the coming off of paint is called 'peeling.' So, option D is correct. 'Tanning' is coloring, not removal. 'Varnish' is outer coating or veneer. 'Baste' is to moisten meat with fat during roasting.

'Isobars' and 'isotherms' are lines on weather maps which represent patterns of pressure and 'temperature', respectively. 'Isotherm' connects points with equal 'temperature'; 'isobar' connects points with equal 'pressure.' Thus, option 1 is correct.
Volume, density and viscosity are units of measure which do not fit in the above analogy.

Both 'genuine' and 'authentic' mean 'original'. While 'spurious' means 'false or fake', so does 'phony'.
So, option A is the correct answer.

An isthmus is a narrow strip of land connecting two large land masses; strait is a narrow waterway connecting two large water bodies.

'Mermaid' is supposedly half 'fish', half human; 'Centaur' is supposedly half 'horse', half human. Both 'mermaid' and 'centaur' are 'mythical creatures'. No other option displays this analogy.
Therefore, the answer is option D.

Somebody who is indigent is a 'pauper.'
Somebody who is diplomatic is a good 'negotiator.'

Major and Squadron Leader are equivalent ranks in Army and Air Force respectively, and so are Lieutenant and Flying Officer.
