Question

8. The entry ticket for an exhibition is Rs 5 for children and Rs 15 for adults. A group of thirteen persons visited this exhibition and paid Rs 115 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.
