A can work three times faster than B. A takes 60 days less than B to do a work. Find the number of days it would take to complete the work if both work together.
A. \(22\frac{1}{2}\) days
B. 32 days
C. \(24\frac{1}{3}\) days
D. 26 days
Explanation: ধরি, B কাজটি করতে \(x\) দিন সময় নেয়। A কাজটি করতে \(x/3\) দিন সময় নেবে।\nপ্রশ্নানুসারে, \(x - x/3 = 60 \Rightarrow 2x/3 = 60 \Rightarrow x = 90\)\nB কাজটি 90 দিনে করে। A কাজটি \(90/3 = 30\) দিনে করে।\nএকসাথে A এবং B এর 1 দিনের কাজ = \(\frac{1}{30} + \frac{1}{90} = \frac{3+1}{90} = \frac{4}{90} = \frac{2}{45}\) অংশ।\nকাজটি শেষ করতে সময় নেবে = \(\frac{45}{2}\) দিন = \(22.5\) দিন বা \(22\frac{1}{2}\) দিন।]
