Question

Louisa invited many children to her birthday party. Half
of her guests were from the neighbourhood. The
remaining half was her classmates. The rest were her 10
close friends. How many guests did she invite ?​

Answer 1

She invited 40 guests

Step-by-step explanation:

Let x be the total number of guests invited by Louisa,

Since, half of her guests were from the neighbourhood,

So the guests from neighborhood = $\frac{x}{2}$

Remaining guest =  $x-\frac{x}{2}=\frac{2x-x}{2}=\frac{x}{2}$

Again, the remaining half was her classmates,

Classmates = $\frac{x/2}{2}=\frac{x}{4}$

Remaining guests = $\frac{x}{2}-\frac{x}{4}=\frac{2x-x}{4}=\frac{x}{4}$

According to the question,

$\frac{x}{4}=10$

$x=4\times 10$

$x=40$

Hence, she invited 40 guests.
