Answer: (b)
Step-by-step explanation:
Given
R is inversely proportional to A i.e
![R\propto \dfrac{1}{A}\\\\R=\dfrac{C}{A}\quad [\text{C=Constant}]](https://tex.z-dn.net/?f=R%5Cpropto%20%5Cdfrac%7B1%7D%7BA%7D%5C%5C%5C%5CR%3D%5Cdfrac%7BC%7D%7BA%7D%5Cquad%20%5B%5Ctext%7BC%3DConstant%7D%5D)
when 
Insert the values to get C

When A=250

option (b) is correct
Answer:
it is simple those are linear equation.
u multiply 2 to 5 then find its lcm u'll get the answer.
Answer:
correct answer is x = 2.75
Step-by-step explanation:
Given;
AB = 2x-5
BC = 6x
AC = 27
Hence,
=> AC = AB + BC
=> 27 = 2x-5 + 6x
=> 27 = 8x-5
=> 27-5 = 8x
=> 22 = 8x
=> 22/8 = x
=> 11/4 = x
or
2.75 = x
