<h2><u>Given</u> :</h2>
The given equations are :


Let's solve for g in equation (2) :


now, let's plug value of g from equation (3) into equation (1) :





plugging value of b in equation (3) :



since " g " represents ground seats, number of ground seats :
=》396
And " b " represents balcony seat, therefore it is equal to :
=》312
