Question

The average of five numbers is 15. Four of the numbers are 11,18,17, and 14. What is the sun of the five numbers?

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.
