Solution

If $$\frac{(d -3n)}{(7n - d)}= 1$$ which of the following statements describes d in terms of n?

Here we have $$\frac{(d -3n)}{(7n - d)}= 1$$ which can be rewritten as $$d -3n = 7n -d$$. Bringing all the d to right side and n to the left we have $$2d = 10 n$$.

Thus the right option is d = 5n or d is 5 times n.
