• Average mark by group of 10 students is 41. So the total marks becomes = 10*41 = 410.
  Now add the mark of the new student with the total = 410+63= 473
  Find the new average = 473/11 = 43.

• Number of students is N=10, Average=41, then the total mark equal=41*10=410
  When the new student is added N=11 and the total mark will be 410+63=473
  So the new average is 473/11=43
