Question

In the following questions, a set of figures carrying some numbers is given. The numbers in each figure follow some specific principle. Study the figures to find out the principle on the basis of which the missing number can be derived. Then, choose the correct alternative which contains this missing number.

• A. $5$
• B. $6$
• C. $8$
• D. $9$

Answer 1

The correct option is B $6$

From the figures
$\frac{50+31}{9}=\frac{81}{9}\Rightarrow 9;\frac{42+21}{7}=\frac{63}{7}=9$
$\frac{43+11}{?}=9\Rightarrow \frac{54}{9}=?\Rightarrow 6=?$
Hence, option 'B' is correct
