# Unitary method

The method in which the price of 1 article helps us in finding the price of any number of articles is known as unitary method.

**Note:** if may be noted that: more articles will cost more Cost of any number of articles = (Cost of 1 article) * (number of articles)

Less articles will cost less

**Cost of 1 article** = Cost of given number of articles/number of articles

**Time and Work**

If A can finish a piece of work in a days, the work done by A in 1 day =1/n

If A’s 1 day’s work= 1/n then the time taken by A to finish the work = n days.
