Question

In a cinema hall 300 tickets were sold for a total of 32000. if the tickets were of two denomination of 80 rs and 120 rs how many of each were sold

Answer 1

Step-by-step explanation:

Let 1st ticket =X

2nd ticket =Y

therefore X+Y=500.........1)

15X+30Y=12000.......2)

2nd equation subtract in equation 1.....

then x=200 i.e. 15rs = 200

Y= 300 i.e. 30rs= 300

X — 200*15 = 3000

Y — 300*30 = 9000

X+Y = 500 Tickets

X+Y = 12000 rs
