Question

2 successive price increase of 10%and 10%of an article are equivalent to a single price increase of

Answer 1

Answer: 21%

Step-by-step explanation:

In these types of sums, we can start with 100 as the price.

So, first 10% increase. So the price now becomes 110 (because 10%of 100 is 10 and adding it to 100 gives 110)

Then, another 10% increase. So 10% of 110 is 11. Add it to 110, we get 121.

So, 121-100=21

There has been a net increase of Rs.21

21 is 21% of 100.

Therefore 21% increase would be equal to successive 10% discounts.
