The Entity kids for exhibition is 5 for children Rupees 15 for adult group of 13 person visited this exhibition and paid rupees 155 to buy interest find the number for children and adults smaegroup

Answer 1

Fees for Children = Rs .5

Fees for adults = Rs. 15

Let there be x children and y adults.

No of persons = 13

Hence, x + y = 13 --------------------------------(1)

and, Total rupees paid = Rs. 155

so, 5x + 15y = 155

   x + 3y = 31 -------------------------------------(2)

Solving Eqn. (1) and (2)

x = 4 and y = 9

Hence, no. of children = 4 and no. of adults = 9
