20 cars sold in july ,40 cars sold in august what is the percent increase in number of cars sold.?

20/20*100 = 100% If 2 extra cars were sold the increase would be 2/20*100 = 10%

so you have to find the increase: 40 - 20 = 20 (number of cars increase) makes the increase into percentage: 20/20 X 100% = 100% so your answer is 100%, hope it helps. Good luck.

100% because 20 cars plus 20 cars is 40 right? You increased the sales by 100% because you basically doubled the previous months car sales. If you sold 20 cars in August you would have a 0% increase. If you sold 30 cars in August you would have a 50% sale increase. Since you sold 20 more cars the next month, and 20 is 100% of the previous months sale you have a 100% sale increase.

percent increase = (number august - number july)*100/ number july = 100 %

100

it's a 100% increase (40-20)/20 x 100 = 100%

increase in the no of cars= 40 - 20= 20 percentage= (increase/initial)*100 = (20/20)*100 =1*100 =100%

20 + 20*x = 40 20*x = 20 x = 1 --> 100%

100% bro, that one should be obvious.
