To find the number that will be in the middle after interchanging the first two digits, we need to arrange the given numbers in ascending order based on their original first two digits. Let's analyze each option:
a) 230: After interchanging the first two digits, we get 032, which is the same as 32.
b) 328: After interchanging the first two digits, we get 823.
c) 516: After interchanging the first two digits, we get 615.
d) 138: After interchanging the first two digits, we get 813.
Now, let's arrange these numbers in ascending order based on their original first two digits:
1) 032 (or 32)
2) 823 (or 328)
3) 615 (or 516)
4) 813 (or 138)
We can see that the numbers are already arranged in ascending order based on their original first two digits. So, the middle number after the interchange will be the third number, which is 615 (or 516).
Therefore, the correct answer is option c) 516.
