Data Interpretation Table: Solved Examples

DIRECTIONS: Read the table given below and answer the questions accordingly.

Shares traded on Bangalore, Madras, Bombay Stock Exchanges (In Rupees)

Bangalore Madras Bombay Total
Name of the company High Low High Low High Low High Low
Colgate 438 396 420 395 452.5 413.75 1310.5 1204.75
L & T 148 140 189.5 180 190 180 527.5 500
NEPC Tea 28 22.75 28.25 23 29 24.5 85.25 70.25
Reliance 190.5 177 189 177.5 191.25 177.5 570.75 532
Tata Steel 160 143 158 140.5 161.25 142.5 479.25 426

Examples are as below

For Example 1: The average of the high rates of share in all the three Stock Exchanges for NEPC Tea is

1. Rs.28.42
2. Rs.27.42
3. Rs.29.1
4. Rs.28.93

Solution: 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.

For Example 2: For Reliance, the low rate of share is less than the average of the low rates of shares of the same company, in the Stock Exchange at

1. Madras
2. Bombay
3. Bangalore
4. None of these

Solution: 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.

Some More examples for concept Clarity.

For Example 3: For Tata Steel, the ratio of the high rate of share to the low rate is maximum in the Stock Exchange at

1. Bangalore
2. Madras
3. Bombay
4. None of these

Solution: 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.

For Example 4: The low rate of share in L & T at Madras Stock Exchange bears a ratio, to the total low rate of share of the same company, of

1. 8/19
2. 9/20
3. 11/25
4. 9/25

Solution: 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 4th option.
