x = yz + r

x - r = yz

(x - r )/z = y

So, Answer will be option (D) :-D :lol: :x

When x is divided by y, the quotient is z with remainder r. Which of the following is y in terms of r, x, and z? (Assume both y and z are nonzero.)

A. x – r – z
B. (x+r)/z
C. x/z−r
D. (x−r)/z
E. xr – z

Given that when x is divided y, the quotient is z and remainder is r. This implies x-r is divisible by y and yz=(x-r) or y = (x-r)/z.

Answer D.

\(x = zy+r\)
\(zy = x - r\)
\(y = \frac{x - r}{z}\)

Ans - D.
