N persons in town 1 and in that 50 perc choose A brand means N/2.
In town 2 no of persons choose A brand is 60 out of 100.
From both the towns total 555 choose A brand.
(N/2)+60=555
N=990.
Total no of persons surveyed is N+100(1st town N and 2nd town 100) ie.,990+100

50/100(n)+60/100(100) were totally surveyed,
this number is equal to 555, hence the equation is,
n/2+60=555,
n=990, plus another 100 people were surveyed, hence 990+100=1090

50% (n) + 60% (100 ) = 55% (n + 100)
Solving we get n = 200

1090

total 555 prefer brand a and out of them 60 are from town chottavile so from bedvitile 495 prefer brand a which is 50% of n so
495 = 50% 0f n

n = 990

so total number of people = 990+100

N/2+60=555
(N+120)/2=555
N+120=1110
N=990
Given solve 50 percent people
495
100nof 60 people of another
So 60
In total number people surveys 990+100=1090
