P₁ = Population in the beginning of the year 2015
P₂ = Population in the end of the year 2015
D = Deaths in the year 2015
Then match the terms given in List-I with the mathematical expression shown in List-II.
| List-I | List-II |
|---|
| (a) Risk of mortality in the year 2015 | (i) 2D / (P₁ + P₂) |
| (b) Survival rates from 2015 to 2016 | (ii) P₂ − P₁ |
| (c) Crude death rate per person | (iii) D / P₁ |
| (d) Survivors of the year 2015 | (iv) P₂ / P₁ |
Choose the correct option:
| (a) | (b) | (c) | (d) |
|---|
| A | (iv) | (ii) | (i) | (iii) |
| B | (iii) | (iv) | (i) | (ii) |
| C | (i) | (iii) | (iv) | (ii) |
| D | (iv) | (ii) | (iii) | (i) |
