Question

a student has to score 60% to pass exam he scores to 225 marks and failed by 15% find the maximum marks of exam​

Answer 1

Answer:

500

Step-by-step explanation:

Let maximum marks of exam=x

Passing percentage=60%

Passing marks=$\frac{60}{100}x$

Score marks=225

Failed by 15%

We have to find the value of x

According to question

$\frac{60x}{100}=225+\frac{15x}{100}$

$\frac{60x}{100}-\frac{15x}{100}=225$

$\frac{60x-15x}{100}=225$

$\frac{45x}{100}=225$

$x=225\times \frac{100}{45}=500$

Hence, the maximum marks of exam=500
