Of the 800 employees of Company X, 80 percent have been with the company for at least ten years. If y of theselong-termmembers were to retire and no other employee changes were to occur, what value of y would reduce the percent oflong-termemployees in the company to 70 percent ? | [
"266.67",
"112",

After y of them retire new # oflong-termemployees would become 640-y.
Total # of employees would become 800-y.
We want 640-y to be 70% of 800-y --> 640-y=(800 -y)*70% --> y = 266.67.

4 / 4 - 3 / 4 = 1 / 4 on a TV
But the TV cost her $200. So 1 / 4 of her savings is $200. So her original savings are 4 times $200 = $800

The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number? | [
"Cannot be determined",
"56",
"54",
"96"
] | A | Answer: Option D
Let the ten's digit be x and unit's digit by y
Then, x + y = 15 and x - y = 3 or y - x = 3
Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6
Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9
So, the number is either 96 or 69.
Hence, the number cannot be determined. | AquaRat_train |

Given that N/J = 134.08
Here 134 is the quotient.
Given that Remainder = 18
So, 134.08 = 134 + 18/J
