3, 5, 10 এবং x এর গড় হল 5
8, 12, 15, x এবং y এর গড় হল 9
ধারণা:
সংখ্যার একটি সেটের গড় হল প্রদত্ত সংখ্যার সংখ্যা দ্বারা ভাগ করা সংখ্যার যোগফল।
গণনা:
⇒ প্রথম শর্ত অনুযায়ী, x = 45 - (3 + 5 + 10) = 20 - 18 = 2
⇒ দ্বিতীয় শর্ত অনুযায়ী, y = 59 - (8 + 12 + 15 + 2) = 45 - 37 = 8
অতএব, x এবং y এর মান হল যথাক্রমে 2 এবং 8
