Question

Replace the question mark in the above problem with the appropriate number.​

Answer 1

Answer: 6.

All of the numbers in every row and column add up to 15! (Also, 6 is the only number not represented out of numbers 1 through 9.)

Answer 2

Given,

The diagram.

To find,

The number in the place of '?'.

Solution,

The number in the place of '?' will be 6.

We can easily solve this problem by following the given steps.

First, let's observe the given diagram very carefully to find the pattern which is being followed. We come to know that there are 3 numbers in each vertical line where in the two full vertical lines the sum of three numbers is 15. (Another way to solve this question is to look at the diagram and observe that the numbers are given from 1 to 9 except one number.)

So, in the second vertical line, we have two numbers whose sum is 9. Then, 6 is to be added to make the sum as 15.

Hence, the number in the place of '?' is 6.
