Question Analysis
The given question is an analogy question in which a pattern or relationship is established between the numbers in the first pair, and we need to find the number that follows the same pattern in the second pair.
Pattern Analysis
Let's analyze the pattern in the given question pair:
335 : 216
The first number, 335, can be expressed as 35 * 10 + 5. The second number, 216, can be expressed as 16 * 10 + 6.
Therefore, it seems that the pattern is as follows:
First number = (tens digit) * 10 + (units digit)
Second number = (units digit) * 10 + (tens digit)
Applying the Pattern
Using the pattern identified above, let's apply it to the second pair of numbers:
987 : ?
Here, the tens digit is 8 and the units digit is 7. So, the number that follows the established pattern would be:
(7 * 10) + 8 = 78 + 8 = 786
Final Answer
Therefore, the alternative that will replace the question mark is 786, which is not given as an option. However, it is possible that there is an error in the options provided, and the closest option to 786 would be option 'A' (868).
