गिरीश ने एक परीक्षा में 572 अंक प्राप्त किए और वह अधिकतम अंकों के 28% से 30 अंक कम था। उसी परीक्षा में उसके मित्र ने 473 अंक प्राप्त किए। उसके मित्र द्वारा प्राप्त अंकों का प्रतिशत क्या है?
Detailed Solution & Logic
22%
Step 1: Find maximum marks
Girish scored 572 and is 30 marks short of 28% of total marks.
So, 28% of maximum marks = $572 + 30 = 602$
Let maximum marks = $M$
$0.28M = 602$
$M = \frac{602}{0.28} = 2150$
Step 2: Friend’s percentage
Friend scored = 473
Percentage = $\frac{473}{2150} \times 100$
$= 22%$
Final Answer: 22%
