Study the given pattern carefully and select the number that can replace the question mark (?) in it.

9      18       ?

18     32      79

27     58      46

Option
a) 22
b) 21
c) 26
d) 25

Solution

Logic = (first Number)$ \times 5 = 2nd + 3rd $
Colum I = $ 9\times 5 = 18 + 27 = 45 $
Colum II = $ 18\times 5 = 32 + 58 = 90 $
Colum III = $ ? \times 5 = 79 + 46 = 125 $
$ ? = \frac {125}{5} = 25 $

Answer: 25
