  • 7: left=$ (symbol), right=3 (number) -> No

  • 3: left=7 (number), right=6 (number) -> No

  • 6: left=3 (number), right=* (symbol) -> No

  • 5: left=+ (symbol), right=4 (number) -> No

  • 4: left=5 (number), right=@ (symbol) -> No

  • None of the numbers match the pattern Symbol - Number - Symbol.

    So the total number of such numbers is 0 (None).

    Final Answer

    There are none (0) such numbers in the series.

    This question is based on the five, three-digit numbers given below.

    (Left) 768 712 783 825 874 (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 second digit of the highest number is multiplied with the third digit of the lowest number?

    Refer to the following number and symbol series and answer the question that follows. Counting to be done from left to right only. (Left) 9 4 ^ 3 7 7 ? 1 \ 2 8 8 \ 7 $ > 3 # ? # ?
