Question

IN AN EXAMINATION 72 PERCENTAGE OF THE TOTAL EXAMINES PASSED.IF THE NUMBER OF FAILUREES IS 392,FIND THE TPTAL NUMBER OF EXAMINES

Answer 1

Fail % = 100-72=28%

$\frac{28}{100} X (total)=392$

$total=\frac{39200}{28} =1400$

Answer 2

Let the total number examines who appeared for the exam be 100

Out of 100, examines who passed are 72

Hence the number of examines who failed are 100 - 72 = 28

Given that the number of examines failed = 392

⇒ Value of 28 = 392

Therefore 1 = $\frac{392}{14}$

1 = 14

⇒ 100 = 1400

Hence 1400 examines had given the exam
