The price of a bike was increased by 10% and then again increased by 8% . The net percentage increase in the price of the bike is:

Correct option is C

Given: ​

First increase in the price of bike = 10% 

Second increase =  8% 

Formula Used: ​

Net percentage = $$x+y+\frac{xy}{100}$$ 

Solution: ​

x = +10%(increase),  y = +8%(increase) 

net increase  = 

$$10+8+\frac{10 \times 8}{100} \\ \ \\ = 18+0.8 \\ \ \\ =18.8 \%$$​​
