A 112 meter rope is cut into three pieces with each piece twice as long as the previous one. How long is the longest piece?
A. 56
B. 64
C. 68
D. 72
Explanation: মনে করি, সবচেয়ে ছোট টুকরোটি \(X\). অতএব, বাকী দুটো টুকরো যথাক্রমে \(2X\) and \(4X\). According to the question, \(X+2X+4X=112 \Rightarrow 7X=112 \Rightarrow X=16\). Therefore, the longest piece \(= 4X = 4\times16 = 64\).
