I've seen this question on Brainly before, and I always shake my head.
Please think about this for a few seconds. Maybe even make some
scribbles on a piece of paper.
-- A triangle has 3 sides and 3 angles.
-- A square, rectangle, rhombus or parallelogram has 4 sides and 4 angles.
-- Draw anything with 5 sides. It doesn't have to be pretty, and they don't
all have to be the same length or anything special. Just draw any shape
with 5 sides. Count the angles, and you'll find that there are five of them.
By now you should be starting to get the creepy hunch that maybe a
polygon always has the SAME number of sides and angles. I hope so.
That's the correct creepy hunch.
You can get all kinds of hunches, and even work most of them out,
just by using your thinker for a while.

(c) 180
(d) 600
Step-by-step explanation:
If there are no restrictions, there are 10 possible values for each digit of a three-digit number.
(a) The leading digit cannot be zero
There are 9 options for the first digit and 10 for the remaining digits.
(b) The leading digit cannot be zero and no repetition of digits is allowed.
(c) The leading digit cannot be zero and the number must be a multiple of 5.
If a number is a multiple of five, it must end in 0 or 5
(d) The number is at least 400.
If the number is at least 400, the first digit can only be 4, 5, 6, 7, 8 or 9. There are no restrictions for the remaining digits.
