Answer 2

Answer:

The original inhabitant of a town are 10000

Step-by-step explanation:

Given:

• Ten percent of the inhabitants of a town have died of plague.
• 25% of the remaining inhabitants left the town

To find: The original inhabitant of a town

Solution:

10% inhabitant were died of Plague in a town.

25% of inhabitant were left the town

Then the population were reduced to 6750.

Let the total number be x.

Then (100-25)% of  (100 -10)% x = 6750

100 -25 = 75%

100 - 10 = 90%

75% of 90%x = 6750

⇒ $\frac{75}{100}$ × $\frac{90}{100} x$ = 6750

⇒75 × 90 × x = 6750 × 100 × 100

⇒ x = $\frac{6750(100)(100)}{75(90)}$

⇒ x = $\frac{67500000}{6750}$

⇒ x = 10000

The original inhabitant = 10000

Final answer:

Therefore the original inhabitant of a town are 10000
