Question

Two lakh sixty-three thousand nine hundred and fifty-three visitors visited the trade fair on Sunday, four lakh and thirty-three thousand visited on Monday, and three lakh twenty thousand six hundred and fifty-six visited on Tuesday. How many visitors in all visited the trade fair in these three days?

Answer 1

Hint: We use the concept of writing the numbers from word form to numerical form. Write all the number of visitors on three days and add the number of visitors in the end.
* In word form, the words lakhs denote \[1,00,000\] ; ten thousands denote \[10,000\] ; thousands denote \[1000\] ; hundreds denote \[100\] ; tens denote \[10\] and ones denote \[1\] where all these are just the idea of places given to the digits.

Complete step-by-step answer:
We are given three counts of visitors on three days of the week i.e. Sunday, Monday and Tuesday.
For Sunday:
We are given that number of visitors are: Two lakh sixty-three thousand nine hundred and fifty-three
We write the number in numeric form
Two lakh sixty-three thousand nine hundred and fifty-three will be written as
 \[2,00,000 + 63,000 + 900 + 53 = 2,63,953\]
For Monday:
We are given that number of visitors are: four lakh and thirty-three thousand
We write the number in numeric form
Four lakh and thirty-three thousand will be written as
 \[4,00,000 + 33,000 = 4,33,000\]
For Tuesday:
We are given that number of visitors are: three lakh twenty thousand six hundred and fifty-six
We write the number in numeric form
Three lakh twenty thousand six hundred and fifty-six can be written as
 \[3,00,000 + 20,000 + 600 + 56 = 3,20,656\]
Now we add the number of visitors obtained from three days
 \[ \Rightarrow \] Total number of visitors \[ = 2,63,953 + 4,33,000 + 3,20,656\]
Calculate the sum in right hand side of the equation
 \[ \Rightarrow \] Total number of visitors \[ = 10,17,609\]

\[\therefore \] Total number of visitors for three days is 10,17,609.

Note:
Many students make mistake of writing the numerical value for the number of visitors on Tuesday wrong as they get confused when there is nothing given for thousands place, keep in mind if we are given no value for any place we just write the value zero, also it states twenty thousand in ten thousands place so we can directly write twenty only.
