To find the ratio of their perimeters, you need to know that the ratio of a perimeter is the square root of the ratio of the areas. (Area is 2 dimensional, so what you do to the perimeter will have twice or be squared for the area).
So, you would simplify the ratio of 18/32 to 9/16.
Then take the square root of 9 and 16 separately to find the ratio of the perimeters.
Square root of 9 is 3.
Square root of 16 is 4
So, the ratio of the perimeters is 3 in/4 in.
Answer:
Ram bought that motorcycle for Rs. 36000
Step-by-step explanation:
Given that:
Amount gained = 25%
Selling price of motorcycle = Rs. 45000
As 100% will be the original price, then 25% will be added into it.
125% will be the new percentage.
Let,
x be the original price of motorcycle.
125% of x = 45000
1.25x=45000
Dividing both sides by 1.25
x=36000
Hence,
Ram bought that motorcycle for Rs. 36000
3x+7=4x
Move the 3x to the other side
7= 4x-3x
7=x
