A shopkeeper has 800 balls of red and blue colors. 480 balls are of blue color. What percentage of the balls are red?
My Answer: D 40%
There where more Blue balls then red and the blue was 60% so i subtracted 480 from 800 and i got 320. 320 wasnt half of 800 so i knew it had to be 40% because blue was 60%. 320/800 x 100= 40%.
800
420= 320 320 divided by 800 = .4
