Question

When integer y is divided by integer z, the quotient is equal to x. Which of the following represents the remainder in terms of x, y, and z?

A. x - yz
B. yz - x
C. y - xz
D. yz - x
E. xz - y

msk0657 · Answer

y = zq+r..we can write the above in this equation form.

Now given quotient is equal to x.

So y = zx + r => r = y - zx.

IMO option C.

Dividend= Divisor*Quotient+ Remainder

y=zx+ Remainder

Remainder= y-zx or y-xz

Hi All,

As complex as this question may look, it can be solved rather easily by TESTing VALUES.

Let's TEST:
Y = 3
Z = 2
3/2 = 1 r 1
X = 1

We're asked for the REMAINDER in terms of X, Y and Z. Thus, we're looking for an answer that equals 1 when we use Y=3, Z=2 and X=1 in the answer choices.

Answer A: 1 - 6 = -5 NOT a match
Answer B: 6 - 1 = 5 NOT a match
Answer C: 3 - 2 = 1 This IS a match
Answer D: 6 - 1 = 5 NOT a match
Answer E: 2 - 3 = -1 NOT a match

Final Answer:  C

We are given that when integer y is divided by integer z, the quotient is equal to x. Thus, we can create the following equation in which r = the remainder:

y/z = x + r/z

Multiplying the entire equation by z gives us:

y = zx + r

y - zx = r

Answer: C

Nunuboy1994 · Answer

We can pick simple numbers and use a simple example- nothing in the question says we actually have to a "remainder" so the remainder could be 0 making the problem easier

X=2
Y=10
Z=5

10-5(2)=0

Thus
"C"
