Question

In an elevator, there are $4$ men, $3$ women, and $6$ children. Each man weighs $150$ pounds, each woman weighs $120$ pounds and each child weighs $60$ pounds. What is the total weight of the people in the elevator?

• A. $1320lb$
• B. $1200lb$
• C. $1000lb$
• D. $1440lb$

Answer 1

The correct option is A $1320lb$

The total weight of the people in the elevator can be expressed as:
$4m+3w+6c$
Where,
$m=$ weight of a man
$w=$ weight of a woman
$c=$ weight of a child
So,
$4m+3w+6c=4\times 150+3\times 120+6\times 60$
$=600+360+360$
$=1320lb$
Therefore, the total weight of the people in the elevator is $1320lb$.
