Two successive price increases of 10% each on an article are equivalent to a single price increase of :

A. 19%

B. 20%

C. 21%

D. 22%

Answer: Option C

Solution(By Examveda Team)

Let the original price be Rs. $$x$$
New final price :
= 110% of (110% of Rs. 100)
= Rs. $$\left( {\frac{{110}}{{100}} \times \frac{{110}}{{100}} \times 100} \right)$$
= Rs. 121
∴ Total increase :
= (121 - 100)%
= 21%
