किसी परीक्षा में, A ने B से 20 अंक अधिक प्राप्त किए हैं । यदि B ने A से 5% कम अंक प्राप्त किए हैं, तो B ने कितने अंक प्राप्त किए हैं?
व्याख्या एवं हल
सही उत्तर (B) 380 है।
व्याख्या:
Let A's score be x. Then B's score is (x-20). Also, B's score is 95% of A's score. Therefore: x-20 = 0.95x. Solving: x = 400. Thus B's score = 380.
