Answer:
Option a is the correct answer
Step-by-step explanation:
![\huge( \sqrt[x]{2})^{ - 1} = {2}^{ - \frac{1}{x} }](https://tex.z-dn.net/?f=%20%5Chuge%28%20%5Csqrt%5Bx%5D%7B2%7D%29%5E%7B%20-%201%7D%20%20%3D%20%20%7B2%7D%5E%7B%20%20-%20%20%5Cfrac%7B1%7D%7Bx%7D%20%7D%20)

Answer:
Share of A is $116 and Share of B is $84.
Step-by-step explanation:
Let the share of A be ![x](https://tex.z-dn.net/?f=x)
Let the share of B be ![y](https://tex.z-dn.net/?f=y)
Given:
$200 is shared between A and B
So, ![x+y =\$200\ \ \ \ equation \ 1](https://tex.z-dn.net/?f=x%2By%20%3D%5C%24200%5C%20%5C%20%5C%20%5C%20equation%20%5C%201)
Also given;
twice of A's share is less than 3 times than B's share by $20
![2x= 3y -20\\2x-3y = -20 \ \ \ \ equation \ 2](https://tex.z-dn.net/?f=2x%3D%203y%20-20%5C%5C2x-3y%20%3D%20-20%20%5C%20%5C%20%5C%20%5C%20equation%20%5C%202)
Solution:
Now multiplying equation 1 by 3 we get,
![3x+3y=600 \ \ \ \ equation \ 3](https://tex.z-dn.net/?f=3x%2B3y%3D600%20%5C%20%5C%20%5C%20%5C%20equation%20%5C%203)
Now Adding equation 2 and equation 3 we get
![(2x-3y = -20)+ (3x+3y=600)\\5x=580\\\\x=\frac{580}{5}=\$116](https://tex.z-dn.net/?f=%282x-3y%20%3D%20-20%29%2B%20%283x%2B3y%3D600%29%5C%5C5x%3D580%5C%5C%5C%5Cx%3D%5Cfrac%7B580%7D%7B5%7D%3D%5C%24116)
Now Substituting the value of x in equation 1 we get,
![x+y=200\\116+y=200\\y=200-116 = \$84](https://tex.z-dn.net/?f=x%2By%3D200%5C%5C116%2By%3D200%5C%5Cy%3D200-116%20%3D%20%5C%2484)
Hence, Share of A is $116 and Share of B is $84.
