Answer 2

Makes obtained by Komal are 588.2

Given - Percentage

Find - Marks obtained by Komal

Solution - Let x be the qualifying marks.

As per the given information about Renu -

300 + 50 = 70%*x

$70\% \times x = 350$

$\frac{70}{100} \times x = 350$

$x = \frac{350 \times 100}{70}$

$x = 500$

Hence, the qualifying marks are 500.

Now, let the marks obtained by Komal be y.

$85\% \times y = 500$

$\frac{85}{100} \times y = 500$

$y = \frac{500 \times 100}{85}$

$y = 588.2$

Hence, Komal obtained 588.2 marks.
