Detailed Solution
Download Solution PDFগণনা:
তিনটি শহরে A এর মোট = 250 + 175 + 350
⇒ 775
গড় = 775/3
⇒ 258.33
তিনটি শহরে B এর মোট = 220 + 190 + 240
⇒ 650
গড় = 650/3
⇒ 216.67
তিনটি শহরে C এর মোট = 260 + 200 + 270
⇒ 730
গড় = 730/3
⇒ 243.33
তিনটি শহরে D এর মোট = 245 + 185 + 330
⇒ 760
গড় = 760/3
⇒ 253.33
সুতরাং, A এর গড় সর্বোচ্চ।
∴ প্রয়োজনীয় উত্তরটি হল A।
