Question

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the value of h? A. 38 С. 40 B. 39 D. 41​

Answer 1

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

`Total=h+(h-2)`

`Total=2h-2`

It is given that the total number of visitors is 80. So,

`2h-2=80`

`2h=80+2`

`2h=82`

Divide both sides by 2.

`h=(82)/(2)`

`h=41`

Therefore, the correct option is D.
