Question

24. The population of a city was 120000 in the year 2013. During next year it increased by 6%
but due to an epidemic it decreased by 5% in the following year. What was its population in
the year 2015?​

Answer 1

Answer:

Answer =120840

Step-by-step explanation:

Total population =120000

increased population=6%

so increased population=6%of 120000

6%×120000 = 7200

now total population=120000+7200

127200.

now population decreased by 5%

so decreased population = 5%of 12720o

decreased population =6360 .

so population in the 2015 year = 127200- 6360

120840.

Answer 2

Answer:

Given:

population of a city in 2013= 120000

it was increased by 6% in 2014

it was decreased by 5% in 2015

To find:

the population in 2015

Step-by-step explanation:

population was increased by 6% in 2014

= 6× 120000

100

by simplification,

6× 1200 = 7200

hence the population in 2014 = 120000+7200=127200

population was decreased by 5% in 2015

= 5 × 127200

100

by simplification,

5 × 1272 = 6360

hence the population in 2015 =

127200- 6360 = 120840

Hence the population in the year 2015 is "120840"
