Answers
Step-by-step explanation:
let the no . of people occupying balcony seat = X
let the no . of people occupying real stall seat = Y
therfore
100X + 75Y = 67500
also X + Y = 800 since there are 800 people totally
4X + 3Y = 2700
X + Y = 800
by solving the above equation we get
X = 300 and y = 600
therefore no. of people occupying real stall seats= y =600
Answer:
300 people occupied Balcony and 500 people occupied Real stall.
Step-by-step explanation:
Given,
- Total number of people = 800
- Total amount collected = 67500 rupees
- X be the number of people in Balcony
- Y be the number of people in real stall
- The price of balcony seat = Rs 100
- The price of real stall = Rs 75
To find :
- The number of people in balcony seat and in real stall.
Solution:
X + Y = 800 .................................(1)
100 X + 75 Y = 67500 .................(2)
100 × equation(1) gives:
100 X + 100 Y = 80000 ..............(3)
Solve equation (3) and (2) : (3) - (2)
And find the value of X and Y
100X + 100 Y = 80000
100 X + 75 Y = 67500
-----------------------------------
25 Y = 12500
-----------------------------------
Y = 500 ....................(4)
Substitute the value of Y in equation (1) and find the value of X
X + 500 = 800
X = 300 ......................................(5)
Therefore 300 people occupied Balcony and 500 people occupied Real stall.
