Question

Ticket rate for the science exhibtion is 10 rupees for a child and 26 rupees for an adult. 740 rupees was got from 50 person. How many children among them?

Answer 1

Answer:

there are 35 children

Step-by-step explanation:

let the number of children be x

let the number of adults be y

total number = 50

x + y = 50 equ (1)

multiply the equation with 10

10x + 10y = 500 equ (2)

charges per child is 10

charges per adult is 26

10x + 26y = 740 equ (3)

subtract (3) - (2) we get

16y = 240

y = 15

substitute y in equ (1)

x + y = 50

x + 15 = 50

x = 50 - 15

x = 35

therefore the number of adults = y = 15

and the number of children = x = 35

hope you get your answer
