Question

The mean of 6 number is 12. Four of them are 12,14,10 and 16. The remaining two are x and x+2. Find the value of x​

Answer 1

Answer:

Total of numbers = Mean X 6

= 12 X 6 = 72

Total of 6 numbers = 12+14+10+16+x + x+2 = 54+2x

54+2x = 72

=> 2x = 72-54 = 18

=> x = 18/2 = 9

Value of x = 9
