CAT 2003 Slot 2 — DILR Question 26
âââââââAnswer the following question based on the information given below.
Below is a table that lists countries region-wise. Each region-wise list is sorted, first by birth rate and then alphabetically by the name of the country. We now wish to merge the region-wise list into one consolidated list and provide overall rankings to each country based first on birth rate and then on death rate. Thus, if some countries have the same birth rate, then the country with a lower death rate will be ranked higher. Further, countries having identical birth and death rates will get the same rank. For example, if two countries are tied for the third position, then both will be given rank 3, while the next country (in the ordered list) will be ranked 5.

In the consolidated list, how many countries would rank below Spain and above Taiwan?
Answer & solution
9
- B
8
- C
7
- D
6
Spain has a birth rate of 18 and a death rate of 8.
Other countries with a birth rate of 18 and a death rate more than 8 = 2 …(i)
Taiwan has a birth rate of 26 and a death rate of 5.
Other countries with birth rate of 26 and death rate less than 5 = 0 …(ii)
Countries with birth rate more than 18 and less than 26 = 7 …(iii)
∴ Countries ranking below Spain and above Taiwan
= equation (i) + equation (ii) + equation (iii)
= 9
Hence, option (a).
