Hello friends, today we will do the
solution to the mathematics question from percentage. So let's start the
solution.

**Solution:**

The cost of the article increased
by 20%, so the 20% of Rs 75 will be:

75x20/100=15

So, after increasing the price
became: (75+15) = 90

Later, the price reduced by 20%, so
the 20% of 90 will be:

90x20/100= 18

Now the present price of the
article will be: (90-18) = 72
