Inâ 2001, the population in a town was 11% more than it was in 2000. if the population was 25,570 in 2002 which was 10% more than 2001 find the population in 2000
write the number (round to the nearest wholeâ number.)

There was population of  22808 in 2000.

Step-by-step explanation:

Since we have given that

Population was in 2002 = 25,570

According to question, the population in 2002 was 10% more than 2001.

So, the population in 2001 was

Now, we have given that

In 2001, the population in a town was 11% more than it was in 2000.

So, population in 2000 was

Hence, there was population of  22808 in 2000.

The question given here has two parts and each part has to be answered separately. In case of both the multiplications, the answer might look to be huge but by applying a simple technique, anybody can do these multiplications without the help of any calculator.
Now let us take the case of first multiplication that is given:
50000 * 700
= 35000000
In this case all the zeroes present has to be written first and then 7 and 5 should be multiplied and put. This will get the answer easily.
Now we take the second multiplication given:
100 * 123478
= 12347800
In this case also the zeroes are simply put on the right side of the number 123478.
