Answer

To evaluate the expression:

y := ceil(25.0/6) + 30 mod 6 - round(15.0/4);

First, calculate each component:

$25.0/6 ightarrow 4.1667$ , thus $ceil(4.1667) = 5$
$30 mod 6 = 0$
$15.0/4 ightarrow 3.75$ , thus $round(3.75) = 4$

Now substitute these values into the expression:

y = 5 + 0 - 4 = 1.

Thus, the value of y is 1.
