Answer 1

Step-by-step explanation:

$business \: \: 45\%$

$teaching \: \: 27\%$

$medical \: \: \:2940$

$total\: percentage \: is \: 35\%$

Here ,number of medical members are 2940

percentage of medical professional is (100-(business+teaching))

= 100-(45+27)

=100-72

=28 percent

So 28 percent is 2940

28 percent = 2940

1 percent = ?

2940/28=105

business = 45 percent = 45×105 = 4725

teaching = 27 percent = 27×105 = 2835

Total working people = 2940+4725+2835

= 10500

Given 35 % is working people

So 35% = 10500

100% = ?

(100×10500)/35=30,000

Total population in the city is 30,000
