Hello kumar brahma
Let the volume of  mixture of CO be a ml
the volume of mixture be b ml
therefore a+b=60ml
Now CO + ½ H2 gives CO2
and then H2 + ½ O2 gives H2O
Afer cooling,the volume is found to be 30ml
therefore
a+{40-(a/2 + b/2)} = 30
afer solving you get
10=b/2 – a/2
b-a=20 ml
therefore
b=40 ml and a=20 ml
Therefore volume of CO=20 ml
and volume of H2=40ml
THANK YOU
