Mainly, there are **two** types of functions: User-defined functions – These functions are defined by the user to perform a specific task. Built-in functions – These functions are pre-defined functions in Python.

Ans. 2 The different types of functions are as follows: many to one function, one to one function, onto function, one and onto function, constant function, the identity function, quadratic function, polynomial function, modulus function, rational function, signum function, greatest integer function and so on.

A function is **a relationship which explains that there should be only one output for each input**. It is a special kind of relation(a set of ordered pairs) which obeys a rule, i.e. every y-value should be connected to only one y-value.

Mainly, there are **two** types of functions: User-defined functions – These functions are defined by the user to perform a specific task. Built-in functions – These functions are pre-defined functions in Python.

Sass include various function for **string, numeric, list, map, selector and introspection**.

There are **two** types of functions in C programming: Library Functions: are the functions which are declared in the C header files such as scanf(), printf(), gets(), puts(), ceil(), floor() etc. User-defined functions: are the functions which are created by the C programmer, so that he/she can use it many times.

There are **three** types of user-defined functions in SQL Server: Scalar Functions (Returns A Single Value) Inline Table Valued Functions (Contains a single TSQL statement and returns a Table Set) Multi-Statement Table Valued Functions (Contains multiple TSQL statements and returns Table Set)

**C++ User-defined Function Types**

- Function with no argument and no return value.
- Function with no argument but return value.
- Function with argument but no return value.
- Function with argument and return value.

If your question is “Can an average student crack IAS?”, then the answer is **YES**! We present a few success stories of some aspirants who were “average” students and yet cleared the exam proving that you need not be a topper to crack the IAS Exam.

**Reconcile the total balances**

- Find the balance of the Creditors Control account.
- Add the balance of any deferred transactions.
- Find the total outstanding balance of your supplier accounts.
- Check for any journals posted directly to the Creditors Control Nominal account.

When the company prepares a bank reconciliation, the outstanding checks are **subtracted from the bank statement balance** in order to determine the correct or adjusted bank balance.

Introduction: This checklist will **guide you through the necessary steps to check your internal financial activity lines up with the financial activity recorded on your bank statement**. It is important to know whether all expected payments have been recorded as this helps you note any potential mistakes made by the bank.

**The following are 12 Types of Estimates used in construction,**

- Preliminary or Approximate or Rough Estimate.
- Plinth Area Estimate.
- Service Unit Method.
- Floor Area Method.
- Carpet Area Method.
- Typical Bay Method.
- Cost Comparison Method.
- Cubic Content Method.

**No, maths is not important or compulsory to become an IAS officer**. Aspiring individuals are required to complete an undergraduate degree programme in any specialisation to become eligible for appearing in UPSC examination.

**The following are different types of cost estimation,**

- Preliminary Cost Estimate.
- Plinth Area Cost Estimate.
- Cube Rate Cost Estimate.
- Approximate Quantity Method Cost Estimate.
- Detailed Cost Estimate.
- Revised Cost Estimate.
- Supplementary Cost Estimate.
- Annual Repair Cost Estimate.

**Major project estimation techniques**

- Top-down estimate.
- Bottom-up estimate.
- Expert judgment.
- Comparative or analogous estimation.
- Parametric model estimating.
- Three-point estimating.

Data reconciliation (DR) is a term typically used to describe **a verification phase during a data migration where the target data is compared against original source data to ensure that the migration architecture has transferred the data correctly**.

Among all the options, analogous estimation is the least accurate, and **bottom-up estimating** is the most precise.

When preparing a bank reconciliation, outstanding checks will: **Decrease the balance per the bank statement**.

Cost estimation models are **mathematical algorithms or parametric equations used to estimate the costs of a product or project**. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms.

You should pick the options such as **Philosophy, Political Science, Psychology, Economics, and Sociology** along with your main subjects after the 10th. They will provide a good base for your preparation for the IAS exam in the future.
