Step-by-step explanation:

Given  

in a class of 32 students 17 have taken maths 10 have maths but not economics.Find the number of students  who have taken maths and economics and the number of students who have taken economics but not maths of it is given that each students have taken either maths or economics or both

A class consists of 32 students.

Students who have taken mathematics = 17

Students who have taken mathematics but not economics = 10

Now students who have taken both maths and economics = students who have taken maths – students who have taken maths but not economics.

                                                          = 17 – 10  

                                                            = 7

So students who have taken economics but not maths = 35 – (10 + 7)

                                                                                      = 35 – 17

                                                                                       = 18
