Refer to the given number and symbol series and answer the question that follows. Counting to be done from left to right only.
How many such symbols are there, each of which is immediately preceded by an odd number and also immediately followed by an odd number?
More than two
None
Two
One
One
Scan the series specifically for symbols and immediately check if the character to the left AND the character to the right are both odd numbers.
Scan the series specifically for symbols and immediately check if the character to the left AND the character to the right are both odd numbers.
Analyze the pattern
We need to find symbols where (Odd Number) - (Symbol) - (Odd Number) occurs. The series is: 5% 4 6 @ 8 7 & 3 ╬й 9 2 \% # 1 * ┬г 5. \text{Symbols are}: \%, @,, &, ╬й, %, #, *, ┬г.
Evaluate each symbol
Let's check neighbors for each symbol: 1) %: 5 and 4 (No); 2) @: 6 and 8 (No); 3) $: 8 and 7 (No); 4) &: 7 and 3 (Yes, both 7 and 3 are odd); 5) ╬й: 3 and 9 (Yes, both 3 and 9 are odd); 6) %: 2 and # (No); 7) #: 2 and 1 (No); 8) *: 1 and ┬г (No); 9) ┬г: * and 5 (No).
Final count
The qualifying combinations are (7 & 3) and (3 ╬й 9). There are exactly two such symbols.
A: 'More than two' is incorrect as we only found two instances. B: 'None' is incorrect as we found exactly two instances. D: 'One' is incorrect because we identified two valid patterns.
C is correct because the two symbols that are immediately preceded and followed by odd numbers are '&' (7 & 3) and '╬й' (3 ╬й 9), totaling two.
When counting specific patterns in long sequences, always write down the candidates first to avoid missing one or double-counting, especially in exam pressure.
