Question

3/5of the balls in a box are red. The rest are green and yellow. The ratio of the number of green balle
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 ratio of of the number of green balls to the number of yellow number is 5:3.

Let no. of green balls =5 units and no. of yellow balls =3 units.

Their difference =(5−3) units =2 units.

2 units =10

1 units =5

Now, total no. of yellow and green balls in the box =(5+3) units =8 units =8×5=40.

These 40 balls are 52 of the total no. of in the box,

So, 52=4051=2053=60

As, 53 of the balls in the box are red. The number of red balls in the box

Answer 2

Answer:

60

Step-by-step explanation:

3/5 of the balls in the box are red. So we have 60% of the box being red balls.

The other two types take up the remaining 40%. Their ratio to each other is 5 to 3. So 5/8 of 40% (= 25%) is green, and 3/8 of 40% (= 15%) is yellow.

Green minus yellow equals 10… in order for the subtraction to work out like that, we need to have exactly 25 green balls and 15 yellow balls — since 25 - 15 = 10.

Since 25+15 = 40 and that’s 40% of the box, that means that there are 100 balls total. So since we figured out earlier that 60% of the box is red balls, that means we have 60 red balls.
