This question is based on the five, three-digit numbers given below.
(Left) 412 366 307 241 667 (Right)
(Example: 697 – First digit = 6, second digit = 9 and third digit = 7) 
(NOTE: All operations to be done from left to right.)
What will be the resultant if the first digit of the highest number is subtracted from the third digit of the lowest number?

​(Left) 412 366 307 241 667 (Right)

Identify the highest and lowest numbers:

Highest number = 667

Lowest number = 241

First digit of the highest number (667) → 6

Third digit of the lowest number (241) → 1

Subtract the first digit of the highest number from the third digit of the lowest number: (Third digit of lowest) − (First digit of highest)

​= (1 − 6) = −5

Thus, the correct option is: (d)
