Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 253.
Average = sum of the numbers/Total numbers
= (253 + 245 + 325 + 120 + 115 + 2K)/5 = 212
= 1058 + 2K = 1060
K = 1
The average of the numbers 353 + 354 + 225 + 220 + and 110 + 3K = (353 + 354 + 225 + 220 + 113)/5
= 1265/5 = 253
