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
