Q2. (12345679 x 72) = ?
Answer : Option B
Explaination / Solution:

12345679 x 72= 12345679 x (70 +2)
= 12345679 x 70 + 12345679 x 2
= 864197530 + 24691358
= 888888888

Q3. Direction: What should come in place of the question mark (?) in the following number series?
17 21 37 73 137 (?)
Answer : Option D
Explaination / Solution:

The pattern of the Sequence & Series is: 
17 + 22 = 17 + 4 = 21 
21 + 42 = 21 +16 = 37 
37 + 62 = 37 + 36 = 73 
73 + 82 = 73 + 64 = 137 
137 + 102 = 137 + 100 = 237 

So, ? = 137 + 102 = 137 + 100 = 237
