No, this Query will not work. it will throw you an error.
you can not use an aggregate function with a where clause.

if you still want to filter out data whose average makes is greater than 70 then you can use the HAVING clause. as below.

SELECT  Subject, AVG (marks)
FROM Students
GROUP BY Subject
HAVING  AVG(marks) > 70
