Answer:
It would be 20
Step-by-step explanation:
Step 1: Our output value is 25.
Step 2: We represent the unknown value with x
Step 3: From step 1 above 25=100%.
Step 4: Similarly, x=80%.
Step 5: This results in a pair of simple equations:
25=100%(1).
x=80%(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
25/x=100%/80%
Step 7: Again, the reciprocal of both sides gives
25/x=80/100
=20
Therefore, 80% of 25% is 20
