Detailed Solution
Download Solution PDFஎண்களின் சராசரி = எண்களின் கூட்டுத்தொகை/ மொத்த எண்கள்
முதல் 12 எண்களின் சராச 15 ஆகும்
12 எண்களின் கூட்டுத்தொகை = 15 × 12 = 180
புதிய எண் 41 சேர்க்கப்படுகிறது
13 எண்களின் சராசரி = (12 எண்களின் கூட்டுத்தொகை + 13வது number)/13
சராசரி = (180 + 41)/13 = 221/13 = 17
