In this article, we will be solving **HackerRank Day 2: Operators** problem, part of **30 Days of Code**. Majorly, we will use ** Python3** and

**to solve the problem.**

*Java15*#### Objective

In this challenge, you will work with arithmetic operators. Check out the Tutorial tab for learning materials and an instructional video.

#### Task:

Given the meal price (base cost of a meal), tip percent (the percentage of the meal price being added as a tip), and tax percent (the percentage of the meal price being added as tax) for a meal, find and print the meal’s total cost. Round the result to the nearest integer.

#### Example:

- mealCost = 100
- tipPercent = 15
- taxPercent = 8

A tip of 15% * 100 = 15, and the taxes are 8% * 100 = 8. Print the value ** 123** and return from the function.

#### Function Description

Complete the *solve* function in the editor of HackerRank.

Function *solve* has the following parameters:

*int meal_cost*: the cost of food before tip and tax*int tip_percent*: the tip percentage*int tax_percent*: the tax percentage

Returns The function returns nothing. Print the calculated value, rounded to the nearest integer.

**Note:** Be sure to use precise values for your calculations, or you may end up with an incorrectly rounded result.

#### Input Format

There are ** 3** lines of numeric input:

- The first line has a double,
*mealCost*(the cost of the meal before tax and tip). - The second line has an integer,
*tipPercent*(the percentage of*mealCost*being added as tip). - The third line has an integer,
*taxPercent*(the percentage of*mealCost*being added as tax).

#### Sample Input

```
12.00
20
8
```

#### Sample Output

`15`

#### Explanation

Given:

*meal_cost* = 12, *tip_percent* = 20, *tax_percent* = 8

Calculations:

*tip*= 12 and ((12/100) * 20) = 2.4*tax*= 8 and ((8/100) * 20) = 0.96*total_cost*=*meal_cost*+*tip*+*tax*= 12 + 2.4 + 0.96 = 15.36- round(
*total_cost*) = 15 - We round
*total_cost*to the nearest integer and print the result,.**15**

# Complete the 'solve' function below.
#
# The function accepts following parameters:
# 1. DOUBLE meal_cost
# 2. INTEGER tip_percent
# 3. INTEGER tax_percent
#
def solve(meal_cost, tip_percent, tax_percent):
# Write your code here
tip = (tip_percent * meal_cost) / 100
tax = (tax_percent * meal_cost) / 100
total_cost = round(meal_cost + tip + tax)
print(total_cost)
if __name__ == '__main__':
meal_cost = float(input().strip())
tip_percent = int(input().strip())
tax_percent = int(input().strip())
solve(meal_cost, tip_percent, tax_percent)
```
