In a bag, red, blue, and green balls are in the ratio 3:4:5. If there are 48 balls in total, how many are green?
Show answer & explanation
Correct answer: B
Explanation
Red : Blue : Green = 3 : 4 : 5
Total balls = 48
Total parts = 3 + 4 + 5
Total parts = 12
1 part = 48 / 12 = 4
Green balls = 5 × 4 = 20
