Hi Shibal,
You misread Statement 2
(2) The tens digit of k + 4 is 2.
ie K(xyz) + 4=x'y'2
this is possible only when ones is 8. so if ones is 8..then to make y'=3 y must be 2..so its sufficient.

(y+3)(y-1) -(y-2)(y-1)=r(y-1)
if (y+3)(y-1) -(y-2)(y-1)=r(y-1) what is value of y? 1) r^2=25 2) r=5 The[spoiler] OA=E[/spoiler]. I got to OA also. but i have different approach of solving let given eqn be solved to (y-1)(y+3 -y+2 -r)=0 => (y-1)(5-r)=0 it says y=1.. so there is no need for any of the statement. Answer should be D

A = Arithmetic progression with a=2 l=20 n=10
A= 10/2(2+20) = 110
B = Arithmetic progression with a=1 l=19 n=10
B= 10/2(1+19) = 100
A - B = 10
