Answer 1

Answer:

250000*104/100*104/100*104/100

281216

Answer 2

Answer:

Population 3 years ago = 25000

Population increased at the rate of 10%, 15%, 8%

Now, after an increase in 10% of population,

New population = 25000 + 10% of 25000 = 25000+

100

10

×25000=27500

After an increase in 15% of the population,

New population= 27500 + 15% of 27500 = 27500+

100

15

×27500=31625

After an increase in 8% of the population,

New population = 31625 + 8% of 31625 = 31625+

100

8

×31625=34155

Hence, the present population is 34155
