A1) 2,
5x2-1 = 9, 2x2-2=2, 3x8-4=20,Similarly 7x3-2=19.

A2) 14
Let's say A  B = X
Here Logical Reasoning is A*B/2 = X
So 7*4/2 = 14

A3) 126.
Required number=  multiplication of the three numbers on the three sides of the triangle.

A4)  24.
Required number =multiplication of the numbers on the upper side -  multiplication of the numbers on the lower side.
Required number =10x5 - 13x2=24

A5)
Triangle = 4 , Circle = 5,   Square= 3

triangle = 4 , circle = 5,   square= 3.,
the explanation is the same way as in question 4.
