HERE'S THE ANSWER..

___________________________

⏺️Max limit of lift is 630 Kg

⏺️ Heaviest weight 57 Kg

⏺️Lighest weight 3 Kg

♠️ We had given weight of two people , so weight of rest will be

=> 57 + 3 ....... = 630

=> 60 + ...... = 630

=> 570 Kg

⏺️ Rest of have have tolal weight as 570 Kg

⏺️ We know Lighest weight is 3 Kg , so the max number of people will be

=> 570 / 3

=> 190 People

⏺️ And we have 2 person , so total number of max people can be in lift

=> 190 + 2

=> 192 people.

⏺️ So lift can have maximum 192 people

Answer 2

let weight of rest of people be x

so

= 57 + 3 + x = 630
= 60 + x = 630
= x = 570 kg

max people = 570 / 3
= 190

total people
=190 + 2
=192 people
