Question

Find the value of the question mark.

Answer 1

HINT:- To solve this question, we will have to follow a particular pattern which is explained below:-
We can observe that in the first column, when we subtract the second number from the first number, then we gen the third number.
In the second column also, we can observe the very same pattern.
So, to solve this question, we will follow this pattern.

Complete step-by-step solution -
Let us now solve the question.
We will have to follow the pattern mentioned in the hint provided above.
So, the first number in the first column is 9 and the second number is 2.
Now, when we subtract 2 from 9, we get 7, which is the third number.
So, 9 – 2 = 7
Then, when we look at the second column, the first number is 3 while the second number is 1. When we subtract 1 from 3, we get 2, which is the third number.
Therefore, 3 – 1 = 2
Let us now look at the third column.
The very first number is 7. The second number is 6. Now, when we will subtract 6 from 7, we get 1.
That means, the third number in the third column is 1.
Hence, the number that will replace ‘?’ is 1 because, 7 – 6 = 1.

NOTE:- For solving this question, we have to follow the pattern mentioned above as if we will not follow this pattern, then the answer will come out to be wrong. Also, we must follow a particular pattern for solving such questions because such questions can only be solved when we will follow a single pattern.
