Question
When 10% of the population of the school were absent, there were 810 present. How many pupils were on the roll?(1 Point)
Solution
Step 1: Understand that if 10% of the population were absent, then 90% of the population were present.
Step 2: We know that 90% of the total population is equal to 810 (the number of students present).
Step 3: To find the total population (100%), we can set up the equation: 0.90 * Total population = 810.
Step 4: Solve for the total population by dividing both sides of the equation by 0.90.
Total population = 810 / 0.90 = 900.
So, there are 900 pupils on the roll.
