Question

5/6 of the balls in a box are red . The rest are green and yellow. The ratio of green balls to the no. of yellow balls is 8:7. If there are 12 less yellow balls than green balls, How many red balls are there​

Answer 1

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.
