A sporting goods store ordered an equal number of white and yellow balls.The tennis ball company delivered 45 extra white balls,making the ratio of white balls to yellow balls 1/5 :1/6 how many white balls did the store originally order for? a)450 b)270 c)225 d)none of these
Let the initial number of white and yellow balls be 'x'...Tennis ball company delivered 45 extra white balls..therefore the number of white balls is x+45...and the new ratio of white balls and yellow balls is 1/5:1/6..remiving the rational form...we get 6:5 and this is equal to x+45:x ratio...
x+45 6 ------- = --- => 5x+225=6x => x=225 x 5 Therefore store originally order for 225 balls
