A number is a figure or a value to denote the count or quantity of something. The counting numbers or natural numbers include the numerals 1, 2, 3, 4, etc and are the fundamental of a number. Arithmetic is the elementary branch which studies about numbers, their properties, and arithmetical operations. There are basically four operations- additions (+), subtraction (-), multiplication(\(\times\)) and division (\(\div\)). Each operation helps us to calculate how more or less an object than the other. Let’s practice how to solve word problems using these arithmetical operations.
Word Problems Examples
Example 1: Akshit won a lottery of cash prize Rs.157800. He deposited the amount in his bank account. If he had Rs.45000 in his account, what is his current bank balance?
Solution: We have to find the total amount in Akshit’s bank account. Given,
Amount of cash Akshit won by lottery = Rs.157800
Amount Akshit had before winning lottery= Rs.45000
Total amount Akshit have after winning lottery= 157800 + 45000
Akshit have Rs.202800 as his current balance.
Example 2: Babuji bought a car for Rs. 375000. After three years he sold his car and bought new car for Rs. 830000. How much more has Babuji paid for his new car?
Solution: We have to find the price difference. Given,
Cost of old car= Rs. 375000
Cost of new car= Rs. 830000
Price difference between new car and old car = 830000 – 375000
Babuji has paid Rs. 455000 more for his new car.
Example 3: Prateek is a bookworm. He has a home library and he arranges 483 books per shelves. If there are 32 shelves like this, what will be the count of books in Prateek’s library?
Total no. of shelves = 32
No. of books per shelve = 483
Total no. of books in the library = 483 x 32
Prateek has 2415 books in his library.
Example 4: A shoe factory manufactured 66250 shoes in 250 days. How many shoes did it manufacture per day?
Total no. of shoes manufactured= 66250
Total no. of days taken to manufacture 66250 shoes = 250 days
No. of shoes manufactured per day= 66250 ÷ 250
Hence, factory produced 265 shoes per day.
