Answer:
120kg, 72kg and 8kg
Step-by-step explanation:
Given the ratios 15:9:1
total ratio = 15+9+1 = 25
For the ratio of 15
Share = 15/25 * 200
Share = 3000/25
Share = 120kg
For the ratio of 9
Share = 9/25 * 200
Share = 1800/25
Share = 72kg
For the ratio of 1
Share = 1/25 * 200
Share = 200/25
Share = 8kg
