Neetas volvo bus takes 50 boys to a field trip. Some of them take Rs. ...
Understanding the Problem
To solve the problem, we need to find out how many boys purchased the Rs. 20 tickets. We know:
- Total boys = 50
- Total ticket cost = Rs. 2000
- Cost of Rs. 20 tickets = Rs. 20 each
- Cost of Rs. 45 tickets = Rs. 45 each
Setting Up Equations
Let’s denote:
- x = number of boys who took Rs. 20 tickets
- y = number of boys who took Rs. 45 tickets
From the information given, we can create the following equations:
1. Total boys equation:
- x + y = 50
2. Total cost equation:
- 20x + 45y = 2000
Solving the Equations
We can use these equations to find the values of x and y.
1. From the first equation, we can express y in terms of x:
- y = 50 - x
2. Substituting y in the second equation:
- 20x + 45(50 - x) = 2000
3. Simplifying this gives:
- 20x + 2250 - 45x = 2000
- -25x + 2250 = 2000
- -25x = 2000 - 2250
- -25x = -250
- x = 10
Verifying the Solution
Now that we have x, we can find y:
- y = 50 - x = 50 - 10 = 40
Now let's verify the total cost:
- Total cost = 20(10) + 45(40) = 200 + 1800 = 2000
Conclusion
Thus, the number of boys who took the Rs. 20 tickets is indeed 10.
