Answer 2

Answer:

Let the maximum marks be x.

Maximum marks in case of Amir = (10% of x + 30) = x/10 + 30

Maximum marks in case of Sanju = (40% of x - 30) = 2x/5 - 30

Now,

$\frac{x}{10} + 30 = \frac{2x}{5} - 30 \\ = ) \: x + 300 = 4x - 300 \\ = ) \: x - 4x = - 300 - 300 \\ = ) \: - 3x = - 600 \\ = ) \: x = 200$

Hence, the maximum marks required for the exam are 200.

The correct answer is (a) 200.
