Question

. The population of the certain town is given below. Find the rate of growth of the population in 1931,1941,1961, and 1971. Year x : 1931 1941 1951 1961 1971 Population thousands y 40.62 60.80 79.95 103.56 132.65​

Answer 1

Answer:

0%, 49.68%, 29.53% and 28.09%

Step-by-step explanation:

Concept= Growth Rate

Given= The Population in thousand in ta tabular form

To Find= The rate of growth in percentage.

Explanation=

We have been given that the population of the certain town is given below. Find the rate of growth of the population in 1931,1941,1961, and 1971. Year x : 1931 1941 1951 1961 1971 Population thousands y 40.62 60.80 79.95 103.56 132.65​.

The Tabular form of this data will be:

X     1931      1941      1951      1961       1971

Y    40.62    60.80    79.95   103.56   132.65

To find the rate of growth we will subtract the population of that year from the previous year and divide it by the population of previous year.

Rate of growth of Population =

(Year population - Previous year Population)/ Previous year population * 100%

=> 1931:

     0% as the previous data is unknown.

=> 1941:

    rate= (60.80-40.62)/40.62 *100 = 0.49679 *100 = 49.68%

=> 1961:

    rate= (103.56 - 79.95)/79.95 *100= 0.295309*100= 29.53%

=> 1971:

    rate= (132.65-103.56)/103.56 *100 = 0.28089*100 = 28.09%
