The price of an article was first increased by 10% and then again by 20%. If the last increased price be IRS. 33, the original price was:
Let's say its original price is 100
hence after first increment of 10% its value will be 110.
and after second consecutive increment of 20% its value will be 132
so when its value becomes 132 , original price is 100
now when its value becomes 33 , original price will be $$\frac{100}{132} \times 33$$
