Question

Solve the given question \[7589 - ? = 3434\].
A) 4242
B) 4155
C) 1123
D) 11023

Answer 1

Hint: Consider the missing term as \[x\] and solve for it. First, we are going to consider the missing term in the given mathematical expression, and then we are going to send the missing term to one side and the remaining terms in the given expression to one side and then we are going to solve the expression accordingly such that we find the missing term. After we find the missing value in the expression, we are going to substitute it in the expression and verify whether the equation is satisfied with the found value.

Complete step by step solution:
First, let us consider the missing term from the mathematical expression as \[x\]. Then we get
\[7589 - x = 3434\]
Since, we have to find the missing term, let us send variables to one side and the constants to another side. Then we are going to get
\[\Rightarrow 7589 - 3434 = x\]
Then on further simplification, we will get the value of \[x\]. Which is
$\Rightarrow x = 4155$
Therefore, the missing value has been found, lets verify the value by substituting it in the given expression from the question and then verify whether RHS is equal to LHS after substitution.
So, lets substitute
\[\Rightarrow 7589 - 4155 = 3434\]
Let’s perform the operation in the LHS. Then we get
\[\Rightarrow 3434 = 3434\]
Therefore, from above we can say that the missing value found is valid.

Therefore the correct answer is option ‘B’.

Note: Therefore, it is better to substitute the missing values after finding, such that the equations get satisfied in the end, which means the value found is correct, or else there is some error in the missing value that was found.
