Mrs. Febbi bought 2 chicken. The average mass of the 2 chicken was 4.8kg. One of the chicken was 1.24kg heavier than the other what was the mass of the heavier chicken?
4.8 kg – 1.24 kg = 3.56 kg
mass of the one chicken = 3.56 kg : 2 = 1.78 kg (this is same of both)
but the heavier chicken is 1.78 kg + 1.24 kg = 3.02 kg (the answer)
