Answer:
A) 230
B) 250
explanation :- Number of children visited = X
ticket charge for children= 150
charge for x children = 150x
Number of adults visited= Y
ticket charge for adults =400
charge for y adults = 400y
480 tickets were sold
x+y = 480
Rs 134500 was collected
150 x + 400y= 134500
3x+ 8y = 2690
3x+ 3y = 1440
3x + 8y = 2690
5y = 1250
Y= 250
x+y = 480
X = 230
children = 230
Adults = 250
