A class of 60 students has an average score of 75. If 5 new students are added and the class average increases by 1, what is the average score of the 5 new students?
60 छात्रों की एक कक्षा का औसत अंक 75 है। यदि 5 नए छात्रों को शामिल किया जाता है और कक्षा का औसत 1 से बढ़ जाता है, तो 5 नए छात्रों का औसत अंक क्या है?
Detailed Solution & Logic
88
Solution:
Total score of 60 students
$= 60 \times 75 = 4500$
After adding 5 students, total students
$= 65$
New total score
$= 65 \times 76 = 4940$
Total score of the 5 new students
$= 4940 - 4500 = 440$
Average score of the 5 new students
= \frac{440}{5} = 88$
Answer: (D) 88
