Question

on Sunday a restaurant had 100 guests .13 / 20 of the guests were male .how many were female?
explain method

Answer 1

$\boxed{ANSWER...}$

Let the number of female guests be 'x'.

Total number of guests in the restaurant = 100

Number of male guests = 13/20 of 100

According to question ,

No. of male guests + No. of female guests =100

13/20 ×100 + x = 100

13 × 5 + x = 100

65 + x = 100

x = 100-65

x = 35.

$\bf{Therefore , \:the \:number \:of \:female\: guests \:were \:35.}$

Probability of male = 13/20 Total no.of guests = 100  13*5 = 65 20*5 = 100  No.of male = 65  Total no.of female  100-65 = 35
