Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFAverage of numbers = Sum of numbers/ Total numbers
Average of first 12 numbers is 15
Sum of 12 numbers = 15 × 12 = 180
New number 41 is to be added
Average of 13 numbers = (Sum of 12 numbers + 13th number)/13
Average = (180 + 41)/13 = 221/13 = 17
