Answer:
10% fail, 54 boys pass.
Step-by-step explanation:
A boy failing means he didn't pass, therefore those who failed are the rest of the boys from those who didnt pass. In terms of percentages, we can take 100% - 90% (since 90% passed), and find that 10% failed.
If there are 60 boys and 90% of them pass, to find how many boys passed we take 90% of 60. This is equal to (90/100) * 60, which is equal to 54. Therefore, 54 boys passed.
Answer:
i) 10% boys failed.
ii) 54 boys passed
Step-by-step explanation:
Calculating the Percentage of Students Who Fail:
Identify the opposite value:
Passing and failing are opposite outcomes.
Since 90% of the boys pass, then
100% - 90%
= 10% must fail.
Therefore, 10% of the boys fail the exam.
Calculating the Number of Students Who Pass:
Convert the percentage to a decimal:
90% = 90/100 = 0.9
Multiply the decimal by the total number of students:
0.9 × 60 boys = 54 boys
So, 54 boys passed the exam.
