Question

five percent people in a town died due to some diseases and three percent of the remaining left the town if 276450 people are still in the town find the original number of people in the town

Answer 1

__HI__
five percent of the people died is equal to 276450/5 is 55 290

number of people left the town is 3 %
276450-55 290 is equal to 22 11

Answer 2

Answer:

Step-by-step explanation:

Let the total population of the village be X, and let the no. of people died be Y.

• Than, Y =$\frac{X*5}{100}$          equ. (1)

Let the no. of people who left the town be Z,

• Than, Z = $\frac{(X-Y)*3}{100}$
• Z = $\frac{(X - [X*5]/100]*3)}{100}$      from equ. (1)
• Z = $\frac{[(100X - 5X)/100]*3}{100}$
• Z = $\frac{95X * 3}{100*100}$
• Z = $\frac{285X}{10000}$     equ. (2)

So, X = Y + Z + 276450

• X = $\frac{5X}{100}$ + $\frac{285X}{10000}$ + 276450   from equ.(2)
• X - $\frac{5X}{100}$ - $\frac{285X}{10000}$ = 276450
• $\frac{10000X - 500X - 285X}{10000}$ = 276450
• $\frac{9217X}{10000}$ = 276450
• X = $\frac{276450*10000}{9217}$
• X = 299935

So, the original number of people in town was 299935.
