1. Salary typically consists of Basic DA and other allowances. It all depends on the nature of the company and according to its business policy. 
2. It must not be difficult to get the salary break as it is provided to all the employees at the time of joining and on payment of salary every month 
Please correct me if the above solution has an alternative view. 

In addition to reply by Mr. Suresh,

Salary break up is also available in the Annexure attached to Form 16 Salary certificate provided by employer after the year end.
