3, 5, 10 और x का औसत 5 है।
8, 12, 15, x और y का औसत 9 है।
अवधारणा:
संख्याओं के समूह का औसत, संख्याओं के योगफल को संख्याओं की कुल संख्या से विभाजित करने पर प्राप्त होता है।
गणना:
⇒ पहली स्थिति से, x = 45 - (3 + 5 + 10) = 20 - 18 = 2
⇒ दूसरी स्थिति से, y = 59 - (8 + 12 + 15 + 2) = 45 - 37 = 8
अतः x और y का मान क्रमशः 2 और 8 है।
