Answer 1

Answer:

51.8 %

Step-by-step explanation:

the price of an article increased by 10%, 15% and 20% is 3 in three consecutive weeks what is the approximate over overall percentage increase for the three weeks​

Let say Initial price of article = 100X

Price increased in 1st week = (10/100) * 100X = 10X

Price after 1 week = 100X + 10X = 110X

Price increased in 2nd week = (15/100) * 110X = 16.5X

Price after 2 week = 110X + 16.5X = 126.5X

Price increased in 3rd  week = (20/100) * 126.5X = 25.3X

Price after 3 week =  126.5X + 25.3X = 151.8X

Overall increase = 151.8X - 100X = 51.8X

% increase overall = (51.8X/100X) * 100 = 51.8 %

overall percentage increase for the three weeks​ = 51.8 %
