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:

the answer is 60

Step-by-step explanation:

Green and Yellow balls are in the ratio of 5:3.

Let 5x be number of green balls and 3x be number of yellow balls.

We have, 5x - 3x = 10

Therefore, x=5.

Total number of green and yellow balls combined = 8x = 8*5 = 40

40 are 2/5 of total balls in box.

Total balls in box = 40*5/2 = 100

Red balls are 3/5 of total balls in box.

Therefore, total number of red balls in box are

3/5 * 100

= 60
