##ANSWER##

Total heights of students of class=20× 105cm

=2100 cm.

total heights of new group of students of class= 10× 120 cm= 1200 cm.

total students=20 + 10= 30.

total heights of students=2100 + 1200= 3,300 cm.

New average height of students=their total heights/total no.of students

= 3,300/ 30cm

= 110 cm.

hope this methodology helps you in your problem...
