1.	In an examination Mohit obtained 20% more marks than Sushant but are 10% less than Rajesh. If the marks obtained by Sushant are 1080, find the percentage of marks obtained by Rajesh, if the full marks are 2000. (a) 72% (b) 86.66% (c) 78.33% (d) 75%
Answer» (a) 72% Sushant’s marks = 1080 Mohit’s marks =\(\frac{120}{100}\)x 1080 = 1296 Let Rajesh’s marks be x. Then, \(\frac{90X}{100}\) = 1296 \(\Rightarrow\) x = 1440 \(\therefore\) Percentage of Rajesh’s marks = \(\frac{1440}{2000}\) x 100% = 72%

Answer»

(a) 72%

Sushant’s marks = 1080

Mohit’s marks =\(\frac{120}{100}\)x 1080 = 1296

Let Rajesh’s marks be x. Then,

\(\frac{90X}{100}\) = 1296 \(\Rightarrow\) x = 1440

\(\therefore\) Percentage of Rajesh’s marks = \(\frac{1440}{2000}\) x 100%

= 72%
