Correct option is B
Given:
Five 3-digit numbers:
614, 457, 249, 625, 150
Step 1: Identify the highest and lowest numbers
Highest number = 625
Lowest number = 150
Step 2: Extract the second digits
Second digit of 150 = 5
Second digit of 625 = 2
Now subtract:
5 (from 150) − 2 (from 625) = 3
Option B is correct.
