Answer
9
Step 1: Our output value is 300.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,300=100%
Step 4: Similary, x=3%
Step 5: This result in a pair of simple equations:
300=100%(1)
x=3%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS ( right hand side ) of both equations have the same unit ( % ) we have 300/x=100%/3%
Step 7: Again,the reciprocol of both sides gives
x/300=3/10
x=9
therefore,3% of 300 is 9
