Answer: 300.
Step-by-step explanation: 225/(No denominator) = 75/100.
225 doesn't go in 75. So, 75/100 divided by 5 = 15/20.
I want to find what number you multiply from 15/20 to get 225/(No
denominator). So, I divide 225 by 15. = 15, so multiply 15 x 15 = 225, and
the denominator, 20 x 15= 300.
(Sorry if you don't understand, I don't really know how to explain things.)
But here's your answer!
Answer:
x=1 y=14 they both equal 15
Step-by-step explanation:

Let the actual value of the stool be x.
So if the carpenter sells the stool x rupees he neither loses, now wins anything.
67.50 is the value x - 10% of x, that is:
67.50=x-0.1x
67.50=0.9x
x=67.50/0.9=75 (rupees) is the actual value of the stool.
Selling the stool for 82.50 rupees, the carpenter clearly would make a profit, say of y% of that actual value, that is y%*75.
So using the same method:
82.50=75+y%*75
y%*75=82.50-75=7.5
we can make the calculations, but clearly 7.5 is 10% of 75
Answer: 10% gain.
