Question

The current birth rate per thousand is $32$, whereas the corresponding death rate is $11$ per thousand. The net growth rate in terms of population increase in per cent is given by,

• A. $0.0021\%$
• B. $0.021\%$
• C. $2.1\%$
• D. $21\%$

Answer 1

The correct option is C $2.1\%$

Given, birth rate per $1000$ is $32$ and corresponding death rate is $11$ per thousand.

therefore, net growth on $1000=(32-11)=21$

Hence, net growth on $100=\frac{21}{1000}\times 100=2.1\%$

Therefore, net growth rate in terms of population increase in per cent is $2.1\%$.
