Answer :
→ 9 .
Step-by-step explanation :
We have,
→ Half of number = x / 2 .
→ One third of number = x / 3 .
→ One sixth of the number = x / 6 .
Now, A/Q
°•° Average of the half, one - third and one - sixth .
= ( x/2 + x/3 + x/6 )/3 .
= ( 3x + 2x + x/6 )/3 .
= x/3 .
Now,
==> x - 6 = x/3 .
==> x - x/3 = 6 .
==> 2/3x = 6 .
==> x =18/2 = 9 .
Hence, the required number is 9 .
