Let the number of Rs 2.50 tickets be x and 5.00 tickets be y.

As per the question, x+y = 300 (eq.1)

Also, 2.5x + 5.0x = 1250

         2.5 ( x+2y)  = 1250

                 x+ 2y  = 1250/2.5

                 x+ 2y  = 500  (eq.2)

(eq 2) - (eq 1)

x+2y - x-y = 500-300

              y = 200

Substitute y in eq 1

x+200 = 300

x         = 300-200

       x  = 100

Therefore, there are 100 Rs 2.5 tickets and 200 Rs 5.00 tickets.

Answer 2

Step-by-step explanation:

No. of tickets of rs.2.50= x

No. of tickets of rs.5=y

A.T.Q. x+y =300 ....(1)

also,2.5x+5.0y=1250

2.5(x+2y)=1250

x+2y = 500 ...(2)

Now, eq.(1) -(2)

x+2y-x-y=500-300

y=20

substitution the value of y in eq (1),

x+200=300

x=100...

Therefore,the no. of tickets of rs.2.50 and rs.5.00 is 100 and 200 respectively.
