please explain step by step​

Answer 1

Answer:

50400

Step-by-step explanation:

Present Population= Amount (A) = 50400

Rate % (R)= 5%

Population last year= Principal (P) = ?

Time (T) = 1

Present Population= P(1+5/100)¹

50400= P(21/20)

50400 × 20/21 = P

P = 48000

So, Population in previous year is 50400.
