Question

During 1964, in a certain country, the average number of children eating lunches at school each day was 29336 which represents 74% of the total number of children attending school. Calculate the total number of children attending school in that country?

Answer 1

Answer:

The total number of children attending school was 39643

Step-by-step explanation:

Percentages

To calculate the percentage of a quantity X with respect to another quantity Y, we use the formula:

$\displaystyle P=\frac{X }{Y}*100$

Where Y is the base or reference quantity. If we already know the percentage, but not the base quantity Y, we reverse the formula:

$\displaystyle Y=\frac{X }{P}*100$

During 1964 the number of children eating lunches at school was 29336 per day. We know that quantity is 74% of the total number of children attending school.

We use the above formula to find the base quantity:

$\displaystyle Y=\frac{29336 }{74}*100$

$Y\approx 39643$

The result was rounded to the closest integer.

The total number of children attending school was 39643
