1 Statistics • Mean and Median यदि 10, 5, 6, a और b का माध्य 11 है, तो a + 5 और b - 3 की माध्यिका क्या होगी? If the mean of 10, 5, 6, a and b is 11, then what is the median of a + 5 and b - 3? A. 18 18 B. 20 20 C. 21 21 D. 22 22 उत्तर और व्याख्या देखें Show answer and explanation सही उत्तर: A Correct Answer: A पाँच संख्याओं का योग = 11 × 5 = 55। अतः a + b = 55 - (10 + 5 + 6) = 34। दो संख्याओं a + 5 और b - 3 की माध्यिका उनका औसत होगी: (a + 5 + b - 3)/2 = (34 + 2)/2 = 18। The sum of the five numbers is 11 × 5 = 55. Therefore, a + b = 55 - (10 + 5 + 6) = 34. The median of the two numbers a + 5 and b - 3 is their average: (a + 5 + b - 3)/2 = (34 + 2)/2 = 18.
