#"0.3 N"#

Explanation:

Milli equivalents of #"HCl = 0.3 N × 100 ml = 30 meq"#

Milli equivalents of #"H"_2"SO"_4 = "0.6 N × 200 ml = 120 meq"#

#"30 meq"# of #"H"_2"SO"_4# neutralises #"30 meq"# of #"HCl"#

Left milli equivalents of #"H"_2"SO"_4 = "120 meq - 30 meq = 90 meq"#

Normality of #"H"_2"SO"_4# in final solution

#= "90 meq" / "100 ml + 200 ml" = "0.3 N"#
