Question

The mean of five numbers is 14. Four of
them are 9, 12, 14 and 16. Find the fifth
number.​

Answer 1

Answer:

the average out of 5 numbers is 17 then to know the sum of those numbers one should multiply 17 by 5. After that subtract the four given numbers from this sum, one after the other or calculate the sum of the four numbers and subtract. The answer you get is the fifth number. Like in this particular case 5×17=85. 85-(21+18+17+14)=15.
