Question

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 # ? # ? (Right) How many such symbols are there each of which is immediately preceded by a number and also immediately followed by a number?

• A. Three
• B. Four
• C. One
• D. Two

Answer 1

Answer:

B. Four

There are exactly 4 such symbols.

We are looking for the pattern: Number → Symbol → Number

Let's examine each symbol in the series from left to right:

1. ^ is preceded by 4 and followed by 3 (4 ^ 3) → Match 1

2. ? is preceded by 7 and followed by 1 (7 ? 1) → Match 2

3. \ is preceded by 1 and followed by 2 (1 \ 2) → Match 3

4. \ is preceded by 8 and followed by 7 (8 \ 7) → Match 4

5. is followed by another symbol (>), not a number.

6. > is preceded by another symbol (), not a number.

7. The remaining symbols (# and ?) at the end are next to each other, so they do not satisfy the condition.
