Answer:
Increase the number by 15% of its value. Percentage increase = 15% × 120. New value = 120 + Percentage increase
Step-by-step explanation:
Step 1: In the given case Output Value is 15.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 15 = 100%.
Step 4: In the Same way, x = 120%.
Step 5: On dividing the pair of simple equations we got the equation as under
15 = 100% (1).
x = 120% (2).
(15%)/(x%) = 100/120
Step 6: Reciprocal of both the sides results in the following equation
x%/15% = 120/100
