Hi, here for the given question, here we need to find what is the value for the missing box.
00:08
So here we are given that the digits which we are going to use is 5, 6, 7, 14, 15, 16, 23, 24 and 25.
00:20
So i have added all this.
00:22
So this is equal to 135.
00:24
So now here i will divide 135 with 3 which is equal to 45 which means that sum of each row and column is 45.
00:41
Now here in our case further i will divide 45 with 3.
00:46
So we have value equals to 15.
00:48
So here for the table or the missing square box, i will draw the square box over here which has all 9 digits like this way.
00:57
Okay, so here the middle value will be 15.
01:03
So here this is the middle value which is a mean of all the data.
01:07
So here this is the middle value.
01:12
So further here in our case 15 will be over here.
01:16
We are already given 6 here and we are provided with the 7 over here.
01:22
Now here we know that the sum of all the rows is equal to 45.
01:26
So here i will name this let this be a, b, c, d, e and f.
01:33
So here we know that a plus 15 plus 7 is equal to 45.
01:38
So here solving this we have a equals to 23.
01:43
Now here we know...
