Question
The average of five results is 46 and that of the first four is 45. The fifth result is:Options :11012.550
Solution
The average of five results is 46. This means that the total of these five results is 46 * 5 = 230.
The average of the first four results is 45. This means that the total of these four results is 45 * 4 = 180.
The fifth result is the total of all five results minus the total of the first four results. So, the fifth result is 230 - 180 = 50.
