Answer:
Profit = Rs 100
Profit %age = 6.25%
Step-by-step explanation:
Cost Price = Rs 80
Cost Price for 20 kg = Rs 1600
Selling Price = Rs 85
<u><em>Profit for 1 kg</em></u> = Rs 85 - Rs 80
=> Rs 5 (For 1 Kg)
<u><em>Profit for 20 kg:</em></u>
=> Rs 5*20
=> Rs 100
<u><em>Now Profit %age:</em></u>
=> ![\frac{100}{1600}* 100](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B1600%7D%2A%20100)
=> 0.0625 * 100
=> 6.25%

The text of the question is not visible in the answering window. I'll reproduce it here:
BD bisects <ABC.
m <ABD= 2.5x + 8.6
m<CBD = 3.5x - 3.4
Find m<ABC
Answer:
![m\angle ABC = 77.2^\circ](https://tex.z-dn.net/?f=m%5Cangle%20ABC%20%3D%2077.2%5E%5Ccirc)
Step-by-step explanation:
We have an angle ABC and a line BD bisecting it.
If an angle is bisected, then the two formed angles are congruent, that is
![m\angle ABD=m\angle CBD](https://tex.z-dn.net/?f=m%5Cangle%20ABD%3Dm%5Cangle%20CBD)
Substituting the algebraic expressions for both angles:
![2.5x + 8.6=3.5x - 3.4](https://tex.z-dn.net/?f=2.5x%20%2B%208.6%3D3.5x%20-%203.4)
Subtracting 8.6 and 3.5x:
![2.5x - 3.5x = -8.6 - 3.4](https://tex.z-dn.net/?f=2.5x%20-%203.5x%20%3D%20-8.6%20-%203.4)
Operating:
![-x = -12](https://tex.z-dn.net/?f=-x%20%3D%20-12)
![x = 12](https://tex.z-dn.net/?f=x%20%3D%2012)
The two angles are:
![m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ](https://tex.z-dn.net/?f=m%5Cangle%20ABD%3D2.5x%20%2B%208.6%3D2.5%2812%29%20%2B%208.6%3D38.6%5E%5Ccirc)
![m\angle CBD=3.5x - 3.4 = 38.6^\circ](https://tex.z-dn.net/?f=m%5Cangle%20CBD%3D3.5x%20-%203.4%20%3D%2038.6%5E%5Ccirc)
As expected, both angles have the same measure.
The measure of the total angle ABC is twice any of those:
![m\angle ABC = 2*38.6^\circ=77.2^\circ](https://tex.z-dn.net/?f=m%5Cangle%20ABC%20%3D%202%2A38.6%5E%5Ccirc%3D77.2%5E%5Ccirc)
![\mathbf{m\angle ABC = 77.2^\circ}](https://tex.z-dn.net/?f=%5Cmathbf%7Bm%5Cangle%20ABC%20%3D%2077.2%5E%5Ccirc%7D)
I think it is D, too. Did you submit the test yet?
