Answer:

82.5

Explanation:

Step 1: We make the assumption that 200 is 100 % since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100 % = 200.

Step 4: In the same vein, x % = 165 .

Step 5: This gives us a pair of simple equations:

100 % = 200(1).

x % = 165(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 200/165

Step 7: Taking the inverse (or reciprocal) of both sides yields

x/100 = 165/200

x = 82.5 %
