As you can observe by the pattern that,
321 : 9 - (3 * (2 + 1) = 9)
Similarly,
512 : 15 - (5 * (1 + 2) = 15)
We can say,
751 - (7 * (5 + 1) = 42)
751 : 42
The answer is b. 42
We can solve these type of question only by observing the pattern and practicing such problems.
There is no trick, shortcut or formula involved!
Hope this helps!
