2 student pass exam the difference im % is 5
2student= 5%
percentage 8s mean by 100
so we well multiply 20 on both side
2×20dtudent=5×20
40 student = 100%
total student in class= 40

HEY MATE,

Here is your answer,

Given - • 75% students passed the exam
• If 2 more students pass exam then the passing percentage is 80%.
• 80% - 75% = (5% = 2 students.)
_____________________________

Let the number of total students be x.

=>  \frac{5}{100} \times x = 2

=>  x = \frac{100}{5} \times 2

=>  x = 20 \times 2

=> x = 40

Hope this helps!!!!
