Test: Table Charts - 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%
