Answer 1

Answer:

Step-by-step explanation:

let the cost of adult tickets be a.

and the child ticket be c.

according to the given information 2a+3c=20 and a+c=8+1/2(50 paise)

2(a+c)=17/2*2    (multiplying 2nd equation by 2)

2a+2c=17

2a+3c=20          (first equation)

subtract both and you will get c=3.

substitute this in 2nd equation you will get a=5.

this is the answer.
