Question

An elevator says ‘Maximum weight $400$ kg’. If $4$ people weighing $94$ kg, $66$ kg, $40$ kg, and $75$ kg get in, how much more weight can the elevator still hold?

Answer 1

Step 1: Finding the total weight of $4$ people.

Given: Weight of $4$ people are $94$ kg, $66$ kg, $40$ kg, and $75$ kg.

Total weight of $4$ people $=94+66+40+75$

$\mathrm{carry}-\mathrm{over}1946640+75275$

So, total weight of $4$ people $=275$ kg.

Step 2: Finding the weight elevator still hold.

Maximum weight a elevator can hold $=400$ kg.

Total weight of $4$ people $=275$ kg.

So, more weight elevator can still hold $=400-275$

$=125$ kg

Hence, the elevator can still hold $125$ kg of weight.
