Verified By Collegedunia
The Correct Option is A
Solution and Explanation
We are given that the number is a 4-digit number starting with 4 and ending with either 0 or 5. The choices for the second and third digits are any digits from 0 to 9 (10 options for each).
Thus, the total number of such 4-digit numbers is:
\[
1 \times 10 \times 10 \times 2 = 200
\]
