Column I Column II
(i) The number of corners of a quadrilateral

(B) Constant

(ii) The variable in the equation 2p + 3 = 5 (E) p
(iii) The solution of the equation x + 2 = 3 (C) +1
(iv) solution of the equation 2p + 3 = 5 (C) +1
(v) A sign used in an equation

(A) =

Explenation 

(i) The number of corners of a quadrilateral =4 always, which is a constant

(ii) The variable in the equation 2p + 3 = 5 is p

(iii) The solution of the equation x + 2 = 3 implies x=3-2 or x=1

(iv) solution of the equation 2p + 3 = 5

2p=5-3

2p=2

p=2/2=1
