Question

Population of one town increased by 8% and other town population decreased by 6% then the population of two towns together 45854 what is the population of each town

Answer 1

1st town population=x
increase 8% population=x+x×8/100
=108x/100
2nd town population=x
=x-x×6/100
=94x/100
total of population=45854
(108x/100)+(94x/100)=45854
( 108x+94x)/100 =45854
202x=4585400
x=4585400/202
x=22700
1st town population=108x/100=(108×22700)/100
=24516people
2nd town population=(94×22700)/100
=94×227
=21338people
1st town population =(108×4595)/202
