Question

In a cinema there are 400 seats. If each stall tickets cost
Rs.25 and each balcony ticket cost Rs. 80, find the
number of balcony seats if a "HOUSEFULL' show
collects Rs.15,000.​

Answer 1

Answer:

solved

Step-by-step explanation:

stall tickets  = s

balcony ticket = b

s + b = 400

25s + 80b = 15000

25s + 25b = 10000

55b = 5000

b = 1000/11

Answer 2

Answer:

Number of Balcony Seats 91

Step-by-step explanation:

Let us take Balcony seat as "X"

then Stall seat "400-X"

(80*X)+(25*[400-X]) = 15000

80X + 10000 - 25X = 15000

80X-25X = 15000-10000

55X = 5000

X = 5000/55

X = 91 (Approximately)

Answer Check:

80*91 + (400-91)*25

7280 + 7725

15005 (due to point approximation)
