Final answer:
To find n(Q), we can use the given formulas: n(Q/P) = 4, n(P/Q) = 5, and n(P) = 7. By rearranging the formulas and substituting values, we find that n(Q) = 4.
Step-by-step explanation:
To find n(Q), we can use the given formulas:
- n(Q/P) = 4
- n(P/Q) = 5
- n(P) = 7
First, we can rearrange the formula n(Q/P) = 4 to solve for Q:
n(Q/P) = 4
Q = 4P
Next, we can rearrange the formula n(P/Q) = 5 to solve for P:
n(P/Q) = 5
P = 5Q
Now, we can substitute the value of Q from the first equation into the second equation:
P = 5(4P)
P = 20P
Dividing both sides by 20, we get:
1 = P
Finally, we can substitute the value of P into the formula n(Q/P) = 4 to find n(Q):
n(Q/P) = 4
n(Q/1) = 4
n(Q) = 4
Therefore, n(Q) = 4.
