Answer 2

Answer: The boxer lose 1.8 kg in the final week to get able to compete as a flyweight.

Step-by-step explanation:

Since we have given that

Quantity of weight a boxer needs to lose in a month is given by

$3\frac{1}{2}\ kg\\\\=\frac{7}{2}\ kg=3.5\ kg$

In 3 months, he lowers his weight from 55.5 kg to 53.8 kg.

So, Quantity of weight he lose in three months is given by

$55.5-53.8\\\\=1.7\ kg$

Number of kilograms the boxer lose in the final week to be able to compete as a flyweight is given by

$3.5-1.7\\\\=1.8\ kg$

Hence, the boxer lose 1.8 kg in the final week to get able to compete as a flyweight.
