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

Answer:
8 Liters
Step-by-step explanation:
Percentage of Alcohol in water= 2L X 0 =0
Percentage of Alcohol to be added = xL X 0.9 =0.9x
- New Volume =(x+2) Liters
- Desired Concentration = 0.72%
Therefore:
0+0.9x=0.72(x+2)
0.9x=0.72x+1.44
Collect like terms
0.9x-0.72x=1.44
0.18x=1.44
Divide both sides by 1.44
x=8 Liters
Therefore, Shanice must add 8 Liters of 90% alcohol solution to create the desired mixture
Answer:
D
Step-by-step explanation:
We need to understand the meaning of slope. The slope means the rate of change of y with every unit change of x.
<em>In our case, it will be rate of change of sales increase (%) with respect to unit change of discount(%).</em>
<em />
The formula for slope is the change in y divided by change in x.
From the 2 points given, we can say that slope is:
<em>This means "as discount increases 1%, sales increase by 3%". Option D is right.</em>
It has to be 2.75 as a decimal.
