If the average of 5x and 8y is greater than 90, and x is twice y, what is the least integer value of x ? Choices.
A) 4	B) 5	C) 20	D) 21	E) 23
If y is greater than 110 percent of x, is y greater than 75?   (1)x&gt;75x&gt;75   (2) y−x=10y−x=10   Pls verify.   1) Sufficient.   y &gt; 1.1 x and x &gt; 75. Min(x) = 75   y &gt; 1.1 * 75   y &gt; 82.5   2) Insufficient. Substituting (x=y-10) in y &gt; 1.1x   y &gt; 1.1(y-10)   y &lt; 110   Hence 4.
