The daily rate of a hotel room that accommodates 4 people is Taka 3900 for one person and Taka x for each additional person. If 3 people take the room for one day and each pays Taka 2100 for the room, what is the value of x?
A. 600
B. 800
C. 1200
D. 1300
E. None of these
Explanation: মোট pay করা হলো = 3 × 2100 = Tk 6300. সূত্রানুযায়ী করার কথা = Tk. \(3900 + 2x\). \(3900 + 2x = 6300\) => \(2x = 2400\) => \(x = 1200\).
