Sure, let's find the correct answer for the given problem.
144 : 10 :: 169 : ?
- 144 is a perfect square (12²) and its square root is 12.
- 12 is then reduced to 10 by subtracting 2 (12 - 2 = 10).
- Similarly, 169 is a perfect square (13²) and its square root is 13.
- Following the same pattern, subtract 2 from 13 (13 - 2 = 11).
Thus, the correct answer is:
B: 11- 169 : 11

Question Analysis:
Here, the given question is in the form of a ratio.
The ratio of 144 to 10 can be written as 144/10 = 12.
Similarly, the ratio of 169 to some number can be expressed as 169/x.
Solution:
We need to find the value of x that makes the ratio of 169 to x equal to 12.
This can be done by setting up a proportion:
144/10 = 169/x
Cross-multiplying gives us:
144x = 1690
Dividing both sides by 144, we get:
x = 1690/144
Simplifying further, we get:
x = 11.7361
Since x has to be a whole number, the closest value to 11.7361 is 11.
Therefore, the alternative which will replace the question mark is option B, i.e., 11.
Answer: Option B.
