Question

A survey conducted on an Indian state shows that 1623546 people have only primary education: 9768678 people have secondary education; 6837954 people have higher education and 2684536 people are illiterate. If the number of children below the age of school admission is 698781, find the total population of the state.

Answer 1

Hint: To solve this question, first, we will write the given number of people accordingly given in the question. Then, we will add all the numbers of people from different levels of education by adding the 5 numbers to get the population of the state.

Complete step-by-step solution
Now, in question, there is lots of information given.
So, let us see them one by one.
(1) 1623546 people have only primary education
(2) 9768678 people have secondary education
(3) 6837954 people have higher education
(4) 2684536 people are illiterate
(5) number of children below the age of school admission is 698781
What we are asked to find in question, is the total population of the state.
So, we know that if we add the numbers of people given in question under various categories of types of education, we will get the total population of the state.
So, the total population of state = Number of people have only primary education + Number of people have secondary education + Number of people have higher education + Number of people are illiterate + Number of children below the age of school admission.
So, on putting values we get,
Total population of state = $1623546+ 9768678+ 6837954+ 2684536+ 698781$
On adding two numbers at a time, we get
$= (1623546+ 9768678)+(6837954+ 2684536)+698781$
On simplifying, we get
Total population of State = $21613495$.

Note: To solve such types of questions, one must read questions twice as in this question, there is so much data given with very large digit numbers, so extract all hints and data carefully. Try not to make any calculation mistakes while adding the numbers. It is advised to add two numbers at a time and then proceeds ahead for a solution in the same manner. Also, the population has no units, so end the answer by writing people after the numerical answer.
