Question

3/5 of the balls in a box are red. The rest are green and yellow. The ratio of the number of greenho
to the number of yellow balls is 5:3. If there are 10 less yellow balls than green balls, how many
balls are there?
​

Answer 1

Answer:

there are 100 numbers of ball

Step-by-step explanation:

3/5 of the balls are red means 2/5 are green & yellow

green: yellow = 5:3

let numbers of green ball be 5x and yellow ball be 3x

according to question

5x-3x = 10

=>2x = 10

=> x = 5

therefore total number of green ball is 25 and yellow ball is 15.

so 2/5 unit ----> 40

so 3/5 unit -----> 60

so there is total 100 balls red =60 green = 25 & yellow =15

Answer 2

Step-by-step explanation:

yellow:green is 3:5

To have 10 fewer yellow balls than green, this calculates to 15:25

25+15=40, and 1 - (3/5)=2/5.

So 40 balls make up 2/5ths of the total.

40*(5/2)=100

100-40=60.

There are 60 red balls.
