In a class of 45 students, a child ranks twentieth. When two more children join, he moves down one position. What is his new position from the end?
45 विद्यार्थियों की एक कक्षा में एक छात्र का स्थान ऊपर से 20वाँ है। दो और छात्र प्रवेश लेते हैं, जिससे उसका स्थान ऊपर से एक स्थान नीचे हो जाता है। अंत से उसका नया स्थान क्या होगा?
Detailed Solution & Logic
25
After two students join, total students = 47.
His new rank from the top = 21.
Rank from the end = 47 − 21 + 1 = 27.
व्याख्या: दो छात्रों के आने के बाद कुल छात्र = 47।
ऊपर से नया स्थान = 21वाँ।
अंत से स्थान = 47 − 21 + 1 = 27।
