There are 100800 visitors there altogether in both the buildings.
Let the number of visitors in building b be x.
Visitors in building a will be = 2 x
Now, 2,950 went to a from b.
Visitors in building a = 2 x + 2950
Visitors in building b = x - 2950
ATQ: now a has 39,500 more visitors than b.
We get the equation as:
x - 2950 + 39500 = 2x + 2950
x + 36550 = 2x + 2950
2x - x = 36550 - 2950
x = 33600
2 x = 67200
Total visitors = x + 2x = 33600 + 67200
Total visitors = 100800
Therefore, there are 100800 visitors there altogether in both the buildings.
