Can anyone pls explain how we get 12/30 as answer for the attached file. The best answer will mark as brainliest

Answer 1

Answer:

dear here I your answer

Step-by-step explanation:

In a magic square all the diagonal + coloums+ rows have a same sum so,

first we will see the first row which has

8/30 and 18/30 & a

so now we sum up (8/30 + 18/30) = 26/30

now we will take the second row and do the same

second row :-(10/30 +14/30)=24/30

third row:- (16/30+12/30)=28/30

now we will do the same for coloums and diagonals

diagonals:-

first diagonal:- 10/30+16/30=26/30

second diagonal:- 8/30+10/30+12/30=30/30=1

coloums:-

first coloumn :- 8/30+16/30=24/30

second coloumn:-18/30+10/30=28/30

third coloumn:-14/30+12/30=26/30

now we have all the sumed up nos :-

26/30, 24/30, 28/30 - rows

26/30, 1 - diagonals

24/30, 28/30, 26/30

now we are left with a, b, c

with unknown value

so now we will find their value

to find their value we will take them all and make them same so we need to have the biggest no because we will not have to subtract anything and in magic square addition is done so we will see which is the biggest no

here we see that the second diagonal has all the nos no variable is there and the sum is 1 which is bigger of all so we will try to convert all the nos to 1

so for the first row we see that the sum is 26/30 so we need 4/30 to make it 30/30 which is =1

so here a = 4/30

same we will do with others

second row :- sum is 24/30 so to make it 30/30 we will need 6/30 to make it 30/30=1

so here b=6/30

third row:- sum is 28/30 so to make it 30/30 we will need 2/30 to make it 30/30 which is = 1

so here c=2/30

and in the question it says that the sum of a,b & c is the answer so sum of 4/30 + 6/30 + 2/30= 12/30

I hope it helps you
