One Stop GATE Forum: mistake in solution of test 06 ec?

Message

    In Q1 R is given as xi+yk.So divergence of R should be =1.So the integral R.dS=V 
whereas in the solution the answer is given as 2V. 

Could anybody please confirm?

	in divergence we add d/dx + d/dy i.e. d/dx (x) + d/dy(y) = 2 hope u get that u r commiting thre basic moistake

	in divergence d/dx i +d/dy j + d/dz k so it is dx/dx+dy/dz=1 so the answer shouild be V.
