The average of five numbers is 6.9. If one of the number is deleted, the average of remaining number is 4.4. What is the value of number deleted?

(A+B+C+D+E) / 5 =6.9 (Suppose Equation i)
A+B+C+D+E=6.9*5
A+B+C+D+E=34.5
(A+B+C+D) / 4 = 4.4 (Suppose Equation ii)
A+B+C+D=4.4*4
A+B+C+D=17.6
Put the Value of A+B+C+D in equation (i)
(A+B+C+D+E) / 5 =6.9
17.6+E =35.5
E=34.5-17.6=16.9
