Question

A town’s population increased by 1200 people, and then this new population decreased 11%. The town now had 32 less people than it did before the 1200 increase. Find the original population.​

Answer 1

Answer:

Correct option is

A

10000

Let the population be P.

So, the increased population will be P+1200.

The population after 11% decrease in population becomes P−32.

Therefore,

P−32=(P+1200)−

100

11

(P+1200)

P=10000

So, the total population is 10000.

Answer 2

10000

Let the population be P.

So, the increased population will be P+1200.

The population after 11% decrease in population becomes P−32.

Therefore,

P−32=(P+1200)−

100

11

(P+1200)

P=10000

So, the total population is 10000.
