(1) 29 of the 42 people are employed. (2) 24 of the 42 people are students.

It's straight E. Even when taken together we have:

{Total} = {Students} + {Employed} - {Both} + {Neither} --> we want to calculate: {Both}, # of employed students.

{42} = {24} + {29} - {Both} + {Neither} --> {Both} = 11 + {Neither}, since we don't know # of people who are neither employed nor students, we can not answer the question.

Simple Sets Question: No need to solve the question as in these type ,look for the infor that how many are neither both of them. If the Info is not given ,it cannot be solved. Do not waste your time solving these coz you will waste a few extra seconds.

Prompt Analysis Employed (student) + employed (non student) + non employed (student) + non employed(non student) = 42

Superset employed(student) ranges in 0 - 42

Translation In order to find the exact value, we need: 1# exact value of employed (student) 2# the value of rest of the three parameter 3# 4 equations and 4 mentioned variables.

Statement analysis St 1: Employed (student) + employed (non student) = 29. Cannot say anything about Employed (student). INSUFFICIENT. St 2: Employed (student) + non employed (student) = 24. Cannot say anything about Employed (student). INSUFFICIENT.

ST 1 & St 2: 3 equations and 4 variable. INSUFFICIENT
