Question

Population of the town is 600000 if birth rate is 7.5% and death rate is 4.5% find the population of the town after 3/2 years

Answer 1

Answer:

6,27,000

Step-by-step explanation:

Birth rate per year = 7.5 %

⇒ For 1.5 years, birth rate = 7.5 × 1.5 = 11.25 %

Death rate per year = 4.5 %

⇒ For 1.5 years, Death rate = 4.5 × 1.5 = 6.75 %

Population of town after 1.5 years is:

⇒ Original Population - Death Rate + Birth Rate

⇒ 6,00,000 - ( 6.75% of 6,00,000 ) + ( 11.25% of 6,00,000 )

⇒ 6,00,000 - 40,500 + 67500

⇒ 6,27,000

Hence the population after 1.5 years is 6,27,000.
