Question

The population of a city is 12,00,000 , if it's rate of interest is 4% ,what is the population after 2 years

Answer 1

Answer:

given

the population of a city=1200000

rate of interest=4%

time=2years

$so \\ the \: population \: of \: the \: city \: increase \\ after \: two \: years = \frac{p \times t \times r}{100} \\ = \frac{1200000 \times 2 \times 4}{100} \\ = 12000 \times 2 \times 4 \\ = 24000 \times 4 \\ = 96000$

now

population of the city

after two years=1200000+96000

=1296000

hence the population of the city will be1296000
