Answer 2

The maximum weight that an elevator can accomodate is 800kg. The average adult weight be about 70 kgs with a varience of 200. Yes the lift safely reaches the ground when there are 10 adults in the lift.

Stepwise explanation is given below:

- The maximum weight that an elevator can accomodate is 800kg. The average adult weight be about 70 kgs with a varience of 200.

- It is given that there are 10 adults in the elevator whose each adult's average weight is 70kgs.

- So, 10*70=700

And the maximum weight an elevator can accomodate is 800kg.

- Still 100 kgs of weight is left.

So, yes the elevator can reach the ground safely.
