Solution:

The information on the first statue in the question is confusing and irrelevant.
Statement (1) tells us that:

B=A+10

(

A

is the first and

B

is the second statue).
Statement (2) tells us that:

A+B=80

, therefore we have two equations with two variables and so we can solve the problem. Therefore, both statements are required in order to answer the question.
