GIVEN

75% Passed in English

60% Passed in maths

20% Failed in both subjects

so we can obtain the answer by subtracting the total failed % from 100%

NOTE : they asked overall passing percentage

so first failed % = failed percentage of math
and english

English failed percentage

= 100 - 75 = 25%

in that we should subtract 20 because they given that 20% in both subjects

so 25 - 20 = 5%

english failed percentage = 5%

same for maths

100 - 60 = 40

40 - 20 = 20

maths failed percentage = 20

so overall failed percentage = 20 + 5 +20

= 45


so 100 - 45 = 55

therefore passing percentage = 55%

Passing Percentage Calculation:

To find the passing percentage, we need to consider the students who pass in either English or math or both subjects. Let's break down the given information step by step:

Step 1: Calculate the percentage of students who pass in English.
Given that 75% of students pass in English, this means that 75% of the total students pass in English.

Step 2: Calculate the percentage of students who pass in math.
Given that 60% of students pass in math, this means that 60% of the total students pass in math.

Step 3: Calculate the percentage of students who fail in both subjects.
Given that 20% of students fail in both subjects, this means that 20% of the total students fail in both English and math.

Step 4: Calculate the passing percentage.
To find the passing percentage, we need to consider the students who pass in either English or math or both subjects. This can be calculated using the formula:

Passing Percentage = (Percentage of students who pass in English + Percentage of students who pass in math) - Percentage of students who fail in both subjects

Passing Percentage = (75% + 60%) - 20%
Passing Percentage = 135% - 20%
Passing Percentage = 115%

Therefore, the passing percentage is 115%.

Answer: A) 55%

Note: It is important to note that the passing percentage cannot be more than 100%. However, if the given information is accurate, the question may have been framed incorrectly.
