Answer 1

Solution :-

In First ∆ we have Digits :- 7 --- 4 ---- 3 & inside = 42.

Let See The Logic :-

→ (Down Digit)² - [ (Right digit)² + Left Digit)² ] = xy = Reciprocal of xy = yx = Our Answer .

Check :-

∆ 1 :-

→ (7)² - [ 4² + 3² ]

→ 49 - (16 + 9)

→ 49 - 25

→ 24

→ Reciprocal

→ 42 (Ans).

Similarly, ∆ 2 :-

→ (8)² - [ 6² + 3² ]

→ 64 - (36 + 9)

→ 64 - 45

→ 19

→ Reciprocal

→ 91 (Ans).

Hence, Similarly, ∆ 3 :-

→ 9² - [ 5² + 3² ]

→ 81 - (25 + 9)

→ 81 - 34

→ 47

→ Reciprocal

→ 74 (Ans). = Option D.

Hence, we can say That, 74 is Correct Answer .

Answer 2

|| ✰✰ ANSWER ✰✰ ||

So, In the given question we can see the logic is :-

( Down Number )² - [ ( Right Side Number )² + Left Side Number )² ] = Answer

So, Now using this formula we can solve :-

1 } 7² - [ 4² + 3² ]

= 49 - ( 16 + 9 )

= 49 - 25

= 24 ( Reverse number ) { Actual Number = 42 }

2 } 8² - [ 6² + 3² ]

= 64 - ( 36 + 9 )

= 64 - 45

= 19 ( Reverse number ) { Actual Number = 91 }

3 } 9² - [ 5² + 3² ]

= 81 - ( 25 + 9 )

= 81 - 34

= 47 ( Reverse number ) { Actual Number = 74 }
