Question

Present population of a village is 67600. It has been increasing annually at the rate of 4% . What was the population of the village two years ago?

Answer 1

present population is 67600
so 4%= 4/100 *67600 = 2704

so 2 years means twice of 2704(2704*2)= 5408

so two years ago, the population was (67600-5408)=62192...

Answer 2

Answer:

62500

Step-by-step explanation:

P/(1+R/100)^2

= 67600/(1+4/100)^2

=67600/(104/100)^2

=67600/(26/25)^2

=67600*25*25/26*26

=62500
