10 litre, $2\mathrm{M}{\mathrm{H}}_2{\mathrm{O}}_2$ solution is left open till oxygen gas liberated can burn 20 litre CO gas at STP completely. Another 30 litre, $1\mathrm{M}{\mathrm{H}}_2{\mathrm{O}}_2$ solution is mixed in the above resulting solution. Calculate the volume strength of ${\mathrm{H}}_2{\mathrm{O}}_2$ solution formed.
