Solution

The correct option is E Statement (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
(e)
While at first glance, you may be tempted to answer (c), since there are two linear equations and two variables, as you try to solve the question you will get two answers 30 and 10. So you can’t say which one of those applies to the first school
