Question

two persons together weighed 398/3kg weight of one person is 197/3kg. what is the weight of the second person? ​

Answer 1

Answer:

weight of second person= 201/3 kg

Answer 2

Step-by-step explanation:

Let y be weight of new person

=>Let Average be X

=> (6X-80+y)/6 = X-3

=> 6X-80+y=6X-18

=> y= 80–18

=> y= 62

Or

y = 80–6*3 = 62 ( average is decreased by 3, that means decreased weight(3) is distributed equally among all the person -> 3*(total no of persons) —> 3*6= 18 to be decreased from weight of replaced person
