Then find the total no of people in the village.
Answer» Answer: 300000 Step-by-step EXPLANATION: Let the VILLAGE have X villagers. 62.5% of x SUPPORTED Aamir ⇒37.5% of x supported Bilal Bilal's votes 50% of (Aamir supporters)+70% of (Bilal supporters) =( $\frac{50}{100}$ × $\frac{62.5}{100}$ × $x$ ) + ( $\frac{70}{100}$ × $\frac{37.5}{100}$ × $x$ ) = $\frac{31.25}{100}x$ + $\frac{26.25}{100}x$ = $\frac{57.5}{100}x$ Aamir's votes $\frac{100}{100}x - \frac{57.5}{100} x$ = $\frac{42.5}{100}x$ Given, Bilal won by 45000 votes. So, $\frac{57.5}{100}x-\frac{42.5}{100}x=45000$ $\frac{15}{100}x = 45000$ $x= 45000$ × $\frac{100}{15}$ $x=300000$

Then find the total no of people in the village.

Answer»

Answer:

300000

Step-by-step EXPLANATION:

Let the VILLAGE have X villagers.

62.5% of x SUPPORTED Aamir

⇒37.5% of x supported Bilal

Bilal's votes

50% of (Aamir supporters)+70% of (Bilal supporters)

=( $\frac{50}{100}$ × $\frac{62.5}{100}$ × $x$ ) + ( $\frac{70}{100}$ × $\frac{37.5}{100}$ × $x$ )

= $\frac{31.25}{100}x$ + $\frac{26.25}{100}x$

= $\frac{57.5}{100}x$

Aamir's votes

$\frac{100}{100}x - \frac{57.5}{100} x$

= $\frac{42.5}{100}x$

Given, Bilal won by 45000 votes.

So,

$\frac{57.5}{100}x-\frac{42.5}{100}x=45000$

$\frac{15}{100}x = 45000$

$x= 45000$ × $\frac{100}{15}$

$x=300000$
