Answer:

48 kg

Step-by-step explanation:

Given : Rina lost her weight in the ratio 5:3

            Her original weight was 80 kg

To Find : Her new weight

Solution:

Rina lost her weight in the ratio 5:3

So, Her weight decreased from 5 to 3

$x=\frac{80}{5} \times 3$

$x=48$

Hence her new weight is 48 kg.
