Question

Neeta’s volvo bus takes 50 boys to a field trip. Some of them take Rs. 20 tickets while the rest take Rs. 45 tickets. It the total cost of tickets purchased is Rs. 2000, how many boys took the tickets of Rs. 20 each ?

Answer 1

Answer:

Given :

Total number of boys who went for trip = 50.

Let, the number of students who bought Rs. 20 tickets be x.

Therefore, the number of students who bought Rs 45 tickets = 50 - x

According to the question,

$20x + 45 \: (50x - x) = 2000$

$= > 20x + 2250 - 45x = 2000$

$= > - 25x = 2000 - 2250$

$- 25x = - 250$

$x = \frac{ - 250}{ - 25}$

$x = - 10$

Hence, 10 boys purchased Rs. 20 tickets.

Answer 2

Answer:

Given :

Total number of boys who went for trip = 50.

Let, the number of students who bought Rs. 20 tickets be x.

Therefore, the number of students who bought Rs 45 tickets = 50 - x

According to the question,

20x + 45 \: (50x - x) = 200020x+45(50x−x)=2000

= > 20x + 2250 - 45x = 2000=>20x+2250−45x=2000

= > - 25x = 2000 - 2250=>−25x=2000−2250

- 25x = - 250−25x=−250

x = \frac{ - 250}{ - 25}x=

−25

−250

x = - 10x=−10

Hence, 10 boys purchased Rs. 20 tickets.
