Question

In a test a student got a mark of $49$. His report card showed that he had scored $70$ per cent. What was the maximum mark on the test?

• A. 60
• B. 70
• C. 80
• D. none of these

Answer 1

The correct option is B 70

Let the Maximum mark is $x$

$\therefore 70\%$ of $x=49$

$\Rightarrow \frac{70}{100}\times x=49$

$\Rightarrow x=\frac{49\times 100}{70}=70$
