Question

23. The sum of two numbers is 34, the sixth number is x and the sixth number is 5 times equal to twice the larger number.​

Answer 1

Answer:

If 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.
