What should come in place of question mark (?) in the following number...
Series Analysis:
The given series is a combination of numbers and alphabets. Let's analyze the series step by step:
Step 1:
9 - 2: 9 - 9 : : 9 - 5 : ?
Here, the pattern seems to be that the first number is always 9, and the second number is decreasing by 1 in each step.
Step 2:
9 - 2: 9 - 9 : : 9 - 5 : ?
Let's focus on the alphabets. The alphabets are representing the positions of the alphabets in the English alphabet series.
Step 3:
9 - 2: 9 - 9 : : 9 - 5 : ?
In the first set, the position of 'B' is 2. In the second set, the position of 'I' is 9.
Step 4:
9 - 2: 9 - 9 : : 9 - 5 : ?
In the third set, the position of 'F' is 5.
Step 5:
9 - 2: 9 - 9 : : 9 - 5 : ?
So, the pattern seems to be that the alphabets are representing the positions of the alphabets in reverse order, starting from 'B' and decreasing by 1 in each step.
Step 6:
9 - 2: 9 - 9 : : 9 - 5 : ?
Now, let's find the missing number in the series.
Solution:
The missing number should correspond to the position of 'E' in the English alphabet series, which is 5.
Therefore, the missing number in the series is 9 - 5, which is equal to 4.
Conclusion:
The missing number in the series 9 - 2: 9 - 9 : : 9 - 5 : ? is 9 - 4, which can be represented as option (A) 9 - 6.
