if cost of a notebook is rs 111/4 .how many notebooks can purchase for rs 1179/4?
Answers
or this kind of problem, you'll need to set up a system of equations.
Lets say N represents the number of notebooks the teacher bought, and P represents the number of pencils the teacher bought.
The teacher purchased a total of 460 of both of them, so we can then say that:
N + P = 460
Now if we multiply the price of each by the number purchased to get the total we can say that:
1.75N + 0.05P = 218.50
Now let's solve for 1 variable in terms of the other, lets put P in terms of N
N+P = 460
P = 460-N
... and then substitute that into the other equation
1.75N + 0.05(460-N) = 218.50 multiply out the left side to get
1.75N + 23 - 0.05N = 218.50 pull the 23 over to the right side
1.75N - 0.05N = 195.5
1.70N = 195.5
N = 115
So the teacher purchased 115 notebooks
Hope this helped!
Answer:
Step-by-step explanation:
Cost of 1 notebook=111/4 Rs
No of notebooks purchased in 1 rupee= 1×4/111
