D. The relationship cannot be determined from the information given
If the average of ten numbers is 11, then
\(total/10 = 11\)
therefore, the total sum of those numbers is \(110\).
Using the same principle, the total sum of the six numbers is \(total_{2} = 6*13 = 78\). Due to this, the total sum of the remaining numbers is \(110-78 = 32\), and its average is \(32/4 = 8 = x\).
Finally, replacing,
Quantity A = 40
Quantity B = 8*4 = 32
Quantity A > Quantity B
