First find out K=247 Then find the factor of 247.Knowing its units digit is 7 so one factor's units digit number must be 7 or 3 and 9. Since only 7 and the product of 3 and 9 give us 7 in units digit. Use trial and error method divide 247 by 7,17,3,9,13 and 19 to find out 247 is the product of 13 and 19. Find the average of 13 and 19 which equal to 16.Answer C.
