Question

ticket rate for the science exhibition is 10 rupees for a child 26 rupees for an adult and 740 rupees was got from Fifty Persons how many children among them

Answer 1

Rate for the science exhibition:
for children = ₹10
for adults = ₹26

let the number of children = x
total money from them = 10x

number of adults = 50-x
money from them = (50-x) × 26

Total = 740
=> 10x + 26(50-x) = 740
=> 10x + 1300 - 26x = 740
=> 10x - 26x = 740 - 1300
=> -16x = -560
=> x = -560 / (-16)
=> x = 35

Thus number of children is 35.

Answer 2

Answer:

Rate for the science exhibition:

for children = ₹10

for adults = ₹26

let the number of children = x

total money from them = 10x

number of adults = 50-x

money from them = (50-x) × 26

Total = 740

=> 10x + 26(50-x) = 740

=> 10x + 1300 - 26x = 740

=> 10x - 26x = 740 - 1300

=> -16x = -560

=> x = -560 / (-16)

=> x = 35

Thus number of children is 35.
