Question

what is the answer of number 15 please tell me in full statement ​

Answer 1

Answer:

his original weight is 48 kg

Answer 2

Answer:

His original weight is 5 and it decreased to 3 (as per the ratio). So his weight was 80 kg and decreased weight will be taken as x.

So equation,

5:3::80:x

5/3= 80/x

5x=80*3

x=80*3/5

So,x= 16*3=48 kg
