The entry ticket for an exhibition is 5 ruppes for children and 15rupees for adults.A group of thirteen person visited this exhibition and paid 115 rupees to buy entry tickets.Find the number of children and adults in the said group

Answer 1

Answer:

Let no. of children in the group be x

Then no. Of adults will be 13-x

The charge paid for x no. Of children = 5x Rs

And charge paid for 13-x no. Of adults=(13-x)×15 Rs

Total charge paid by group=115 Rs

So,

5x+15(13-x)=115

5x+195-15x=115

-10x=115-195

-10x= -80

x=8

So no. Of children was 8 and no. Of adults was 5.
