Question

In an examination 15% students failed . If 425 students passed the examination , find the number of students who failed ?

Answer 1

Answer:

15%failed

100-15=85%passed

85%=425

$\frac{425}{x} \times 100 = 85 \\ 42500 = 85x \\ \frac{42500}{85} = x \\ x = 500$

total students=500

failed students =15%

$500 \times \frac{15}{100} = 75$

75 students failed
