1. I load the page
2.input some data
3.click on submit button
4.It does the calculation , and result are shown below in the same page.

In-spite of simplicity wait, page_source doesn't have newly loaded content.

from selenium.webdriver.support.ui import Select
import time 
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from bs4 import BeautifulSoup

driver = webdriver.Chrome('C:\\Users\\Vivekanandhan\\Downloads\\Compressed\\chromedriver_win32\\chromedriver.exe')


driver.get('http://srirangaminfo.com/porutham.php')
#Input Value to the text box
inputElement = driver.find_element_by_id("name2")
inputElement.send_keys('1')

#Select value from the list box 
select = Select(driver.find_element_by_id('fdd2'))
select.select_by_value('4')

select = Select(driver.find_element_by_id('fmm2'))
select.select_by_value('6')

select = Select(driver.find_element_by_id('fyy2'))
select.select_by_value('1986')

select = Select(driver.find_element_by_id('fhr2'))

I tried to get the text from class 'tot blft' but it's giving me an error.

tot = div.find_element_by_class_name('tot blft')
print (tot.text)

That's a different issue.
Am away from my laptop until tomorrow; left it at the office but try:

tot = div.find_element_by_xpath(".//*[@class='tot blft']")
