Question

In an examination, Mohit obtained 20% more marks than Sushant but 10% less than Rajesh. If the marks obtained by Sushant is 1080, find the percentage marks obtained by Rajesh if the full marks is 20

• A. 86.66%
• B. 72%
• C. 78.33%
• D. None of these

Answer 1

The correct option is B 72%

Marks obtained by Sushant is 1080

$Mohi{t}^{\prime }smarks=\frac{120}{100}\times 1080=1296$

$RajeshMarks,R\Rightarrow \frac{90}{100}\times R=1296$

R = 1440

$\%ofRajeshMarks=\frac{1440}{2000}\times 100=72\%$
