Answer 1

Answer:

1)Let’s assume B earns Rs 100 then A earns 90.

Now percentage of difference = 10/90 * 100

= 11.11 %

2)Let the total population be x

100%-(35%+40%)=25% are children

25% of x=28000

25x/100=28000

x=28000*100/25=112000

Total population=112000

men=40% of 112000

=40/100*112000

=44800

women=35% of 112000

=35/100*112000

=39200

Answer:The answer is 112000

Step-by-step explanation:

Men:40%

Women:35%

Children:28000

➡ PERCENTAGE OF CHILDREN:

100-(40+35)

100-75

25%

➡POPULATION:

25(children)×4=100(population)

=28000×4

=112000

Let the number be x

when increased by 8%, the number is x+8%of x=27x/25

when decreases by 7%,the number is x-8%of x=23x/25

ATQ,

27x/25-23x/25=75

4x/25=75

4x=75×25

x=468.75
