Question

On the first day of drama 35 tickets were sold.If the rates of tickets were 20rs and 49rs per ticket and collection was 900rs.find the number of tickets sold of each rate

Answer 1

Let us say no of tickets of rs 20 be x and that of rs 49 be y.

Here x+y=35 and 20x+49y=900,

That is, 20(35-y)+49y=900

That is, 29y=900-700=200

That is, y=200/29=7[rounded off]

So, x=28
