Answer:
D
Explanation:
I don't know the language, but it is clear what is going on.
It looks like you are defining a value for a in both commands.
a.multiply(b); looks like you take the value in a (which is 10) multiply it by 25 and put the result back in a. So so far we have 10 * 25 = 250
Note the next command
a.add(b)
looks like you take the current value in a(which is now 250)
and put the value of b (which has not been changed. It is still 25) and put that in a (which is 250).
The result is 250 + 25 = 275
The answer is D. Since I only understand the logic, if this answer is wrong, I wish you'd leave a note.
