Answer 1

Answer:

Step-by-step explanation:

Suppose the number of tickets x for rs 200 and y for rs100

Total amount received by theatre by sale of tickets is

200x+100y=37000;

x=y+20; as per given condition

Now putting the value of x=y+20 in the equation 200x+100y=37000;

200(y+20)+100y=37000;

300y=37000-4000;

300y=33000;

y=110;

x=y+20;

x=110+20=130

Answer 2

Answer:

110 tickets

Step-by-step explanation:

Define x:

let the number of Rs 100 tickets sold be x

The number of Rs 200 tickets sold = x + 20

Solve x:

Total amount received = Rs 37000

100x + 200(x + 20) = 37000

100x + 200x + 4000 = 37000

300x = 33000

x = 33000 ÷ 300 = 110

Find the number of Rs 100 tickets sold:

Rs 100 tickets = x = 110

Answer: 100 of the Rs 110 tickets were sold.
