24 = 9*2+6
72= 7*9+9
9*5+6 = 51

this is ur answer:

Answer 2

Concept:

There are two kinds of logical reasoning  one is formal deduction second is induction and abduction

Deductive reasoning evaluates whether a conclusion's truth can be shown for that rule only on the basis of the premises' veracity. Example: "Everything outside becomes wet when it rains. Since the grass is outside, it gets wet when it rains." This kind of thinking is frequently related to mathematical logic and philosophical logic.

A finding of the rule is supported by inductive reasoning. After several examples are regarded to be a conclusion that follows from a precondition in terms of such a rule, it hypothesises a rule. For instance: "Grass always gets wet when it rains since it got wet several times when it rained." This kind of reasoning is frequently linked to extrapolating generalisations from empirical data. These arguments could be convincing, but they lack deductive validity—see the induction problem.

Given:

926 : 24

799 : 72

956 : ?

Find:

Which number should replace the question mark?

Solution:

926 24
