2 साल पहले एक नगर की जनसंख्या 62,500 थी। शहरों में प्रवास के कारण, यह हर साल 4%
की दर से कम हो जाती है। इसकी वर्तमान जनसंख्या ज्ञात कीजिए।​

Answer 1

Answer:

57600

Step-by-step explanation:

The population each year decreases by 4%, meaning that there are 1 - 4% = 96% of all of the population in the town staying in the town.

Therefore,

The amount of population in the town 1 year ago

= 62 500 * 96% = 60 000

The present population

= 60 000 * 96% = 57 600

Answer 2

Per year the population decreased by 2500 members. So the present population will be 62500 - 5000 = 57500.
