Question

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

Answer 1

Answer:

100

Step-by-step explanation:

Hence green : yellow= 5 : 3, 5x-3x=10, 2x=10, x=5, green=25, yellow=15, Total balls 5x, Here red balls=3x, green and yellow=2x, Total green and yellow=25+15=40, 2x=40,x=20, 5x=100, Total balls=100

Answer 2

Answer:

there are 60 red ball

Step-by-step explanation:

No. of ball = y  

3/5x = red balls = z  

rest are green and yellow  

Green: Yellow balls = 5:3  

5x and 3x  

green balls are 10 more than Yellow balls  

5x=3x+10  

5x-3x=10

2x=10

x=5  

Green balls = 25 balls (5x)  

Yellow balls = 15 ball (3x)  

Sum of the yellow balls and green balls = 40  

2/5x=40  

x=20*5

=100  

Red balls = 3/5x

=3/5*100 = 60balls  

Therefore , there are 60 red ball
