Question

If a number is increased by 12% and then decreased by 18% then net percentage change in number

Answer 1

Answer:

Step-by-step explanation:

Let it is 100

After 12% increase it becomes 112

Now to reduce 18% of 112

18/100*(112) = 20.16 .

Hence 112-20.16=91.84

Hence 100 increased to 112 then decreased to 91.84.

So 100-91.84=8.16 is the net reduction on 100.

Means 8.16% reduction happened.
