Bags

The first bag weighs 18 kg, the second bag is one-third lighter than the first, and the third bag has three times less than the weight of all three bags. Determine their weights.

Correct answer:

a =  18 kg
b =  12 kg
c =  15 kg

Step-by-step explanation:

a=18=18 kg
b=aa/3=1818/3=12 kg
c=318+12+c  c=(18+12+c)/3  2c=30  c=230=15  c=15=15 kg
