When positive integer x is divided by positive integer y, the remainder is 8. If x/y = 76.4, what is the value of y?  Choose the correct choice from the following answers:
A) 20
B) 22
C) 23
D) 24
E) 25

Rationale: "when positive integer x is divided by positive integer y , the remainder is 8 - - > x = qy + 8 ; x / y = 76.4 - - > x = 76 y + 0.4 y ( so q above equals to 76 ) ; 0.4 y = 8 - - > y = 20 . answer : a ."
Answer: A
