Actually Welcome to the Concept of the Inverse of real function. 
Let's consider here, g(n) = y , 
so we get as,
![y =  \sqrt[3]{ \frac{n - 1}{2} }](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bn%20-%201%7D%7B2%7D%20%7D%20)
no, cubing the power both side we get as, 
=> 

now, 

so finally, we get as,
=> 

hence,here, n = inverse of the g(n) function.
so, 
g^-1 (n) = 2y^3+1.

The ones period consists of the ones, tens, and hundreds digits.
 
        
             
        
        
        
An item that costs $205000, when discounted 15 percent, will cost $174250. The easiest way of calculating discount is, in this case, to multiply the normal price $205000 by 15 then divide it by one hundred. So, the discount is equal to $30750. To calculate the sales price, simply deduct the discount of $30750 from the original price $205000 then get $174250 as the sales price. which mean is C
        
                    
             
        
        
        
(a/b) x (c/d) = (a*c)/(b*d)
Therefore:
(9/4) x (1/3) = (9*1)/(4*3) = 9/12 = 3/4
Answer:
3/4
