Jeeva says June 13, 2017 at 11:52 pm jeevamathaiyan: Solution : 1)A-C = (C-D/2)+(B+D)=(14/2)+2=7+2=9 2)C-D=(A+C)+(B+D)=12+2=14 3)A+C= (C-D)-(B+D)=14-2=12 4)B+D=(C-D)-(A+C)=14-12=2 Reply

Jeeva says June 14, 2017 at 12:00 am Because we already know the values of A-B=9,A+C=12,C-D=14 and B+D=2 based on these values we can solve this problem as per my knowledge Reply

QUESTION SOLV'ER' says December 31, 2016 at 11:14 am a – b=9 + + c – d=14 = = 12 2 a-b = 9 a+c = 12 b+d = 2 c-d = 14 c = 14+d a = 9+b 12 = a+c = b+d+23 = 25 But, 12≠25 So, This question is IMPOSSIBLE. Reply

Felix Denis says March 15, 2016 at 7:08 pm considering the top two squares as a & b, the bottom squares as c & d a = 4.5 b = (-) 4.5 c = 7.5 and d = √ 42.25 (we take the positive integer) Reply

John Townsend says March 15, 2016 at 8:21 pm Close. The puzzle hinges on the fact that a square root has TWO values. Reply

Filipe Mendes de Oliveira says May 5, 2016 at 9:52 pm a = 4.5 b = (-) 4.5 c = 7.5 and d = +-√ 42.2= +6,5 and – 6,5 ???? Reply

Markus says May 10, 2016 at 9:59 am d= √42,25 √ ist not positive or negative for example: 6,5 x 6,5 = 42,25 -6,5 x -6,5 = 42,25 same result so the result of √42,25 can use as a positive or negative result. Sorry for my bad English 🙂 Reply

Jay says May 17, 2016 at 10:28 pm X^2=42.25 will have 2 answer,one positive and one negative. But square root of 42.25 will only result in one positive answer.

jeevamathaiyan:

Solution :

1)A-C = (C-D/2)+(B+D)=(14/2)+2=7+2=9

2)C-D=(A+C)+(B+D)=12+2=14

3)A+C= (C-D)-(B+D)=14-2=12

4)B+D=(C-D)-(A+C)=14-12=2

Jeeva says

Because we already know the values of A-B=9,A+C=12,C-D=14 and B+D=2 based on these values we can solve this problem as per my knowledge

QUESTION SOLV'ER' says

a – b=9

+ +

c – d=14

= =

12 2

a-b = 9

a+c = 12

b+d = 2

c-d = 14

c = 14+d

a = 9+b

12 = a+c = b+d+23 = 25

But, 12≠25

So, This question is IMPOSSIBLE.

Uzma Khan says

1@1=9

2@2=36

3@3=81

4@4=?

Neeha says

144

ravendra Mishra says

?+?=8

? -?=6

= =

Ashok Kumar says

3.5 + 4.5 = 8

9.5 – 3.5 = 6

—– —–

13 8

Svetlana says

9 – 0 = 9

3 – 2 = 14

= =

12 2

My answer 😛

Felix Denis says

considering the top two squares as a & b, the bottom squares as c & d

a = 4.5

b = (-) 4.5

c = 7.5

and

d = √ 42.25 (we take the positive integer)

John Townsend says

Close. The puzzle hinges on the fact that a square root has TWO values.

Filipe Mendes de Oliveira says

a = 4.5

b = (-) 4.5

c = 7.5

and

d = +-√ 42.2= +6,5 and – 6,5

????

Markus says

d= √42,25

√ ist not positive or negative

for example: 6,5 x 6,5 = 42,25

-6,5 x -6,5 = 42,25

same result

so the result of √42,25 can use as a positive or negative result.

Sorry for my bad English 🙂

Jay says

X^2=42.25 will have 2 answer,one positive and one negative. But square root of 42.25 will only result in one positive answer.

du bist deutscher

Roy says

Then 7.5 -√42.25 = -14 not 14

Just asking..
