Question

* During a 10 year period, the number of people living in Sherbury increased by 5% to 20 265

Answer 1

Answer:During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942

Step-by-step explanation:

During the 10 year period,

Let x= increase in the number of

people living in Sherbury

y=number of people living in Sherbury before the increase

Therefore,

5/100 * y = x

0.05y=x

And

x + y = 20265

But y=20x

x + 20x =20265

21x=20265

x=965

During 10years ago the number of people living in Sherbury increased by 965.

Likewise

Let

a=increase in the number of

people living in Yaston

b=number of people living in Yaston before the increase

7.5/100 * b = a

0.075b = a

b=13.33a

a + b = 13502

a + 13.33a=13502

14.33a=13502

a=942

During 10years ago the number of people living in Yaston increased by 942.

Conclusion

During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942.
