The average of 6 numbers is 8 A seventh number is added and the new average is 10 What number was added?
The total of the 6 numbers is 48 (6x8) Adding another number will take the total to 7. So with an average of 10, the total of the 7 numbers will be 70 (7x10) 70 - 48 = 22 which is our seventh number.
The average of six numbers is 19 A seventh number is added and the new average is 20 What is the seventh number?
The sum of the first six numbers is (6 x 19) = 114The sum of the new group of seven numbers is (7 x 20) = 140The seventh number is (140 - 114) = 26.==========================================The seventh number contains enough material to make itself 20and also to raise each of the previous six numbers from 19 to 20.Therefore it must be [ 20 + (6 x 1) ] = (20 + 6) = 26.
