Answer: 3.75
We need to determine 15% of 25 now and the procedure explaining it as such
Step 1: In the given case Output Value is 25.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 25 = 100%.
Step 4: In the Same way, x = 15%.
Step 5: On dividing the pair of simple equations we got the equation as under
25 = 100% (1).
x = 15% (2).
(25%)/(x%) = 100/15
Step 6: Reciprocal of both sides results in the following equation
x%/25% = 15/100
Step 7: Simplifying the above-obtained equation further will tell what is 15% of 25
x = 3.75%
Therefore, 15% of 25 is 3.75
