To find out how many pupils wear spectacles, we need to calculate the percentage of pupils who do not wear spectacles and then subtract this from the total number of pupils.
65 percent of the pupils do not wear spectacles, so the remaining percentage that does wear spectacles is 100 - 65 = 35 percent.
To calculate the number of pupils who wear spectacles, we convert this percentage to a decimal by dividing it by 100: 35 / 100 = 0.35.
Finally, we multiply this decimal by the total number of pupils in the class: 0.35 * 40 = 14.
Therefore, 14 pupils wear spectacles.
In a class of 40 pupils. 65 percent of them do not wear spectacles. How many pupils wear spectacles?
