Answer 1

Given:

एक सभागार मे 1600 सीट है

सभागार मे सीट की कुल 65 पंक्तियाँ है

5 पंक्तियों मे 20 सीट है

अन्य पंक्तियों मे समान सीट है शेष

To find:

शेष पंक्तियों मे कितनी कितनी सीट होंगी ?

Solution:

The total no. of seats in the auditorium = 1600

The total no. of rows of seats in the auditorium = 65

The no. of seats in 5 rows = 20

∴ The remaining no. of rows in the auditorium = 65 - 5 = 60

Let "x" represent the no. of seats in the remaining 60 rows

Now, according to the question, we can form an equation as:

$(5\times 20) + (60\times x) = 1600$

$\implies 100 + 60x = 1600$

$\implies 60x = 1600 - 100$

$\implies 60x = 1500$

$\implies x = \frac{1500}{60}$

$\implies \bold{x = 25}$

Thus, the number of seat in each of the remaining rows is 25.
