সঠিক উত্তর
2 (600 Tk)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Whole work is done by A in (3 × 4) = 12 days
∴ A's 1 day's work = 1/12 part
Whole work is done by B in (4 × 9) = 36 days
∴ B's 1 day's work = 1/36 part
A's 1 day's work : B's 1 day's work
= A's wages : B's wages
= 1/12 : 1/36
= 3 : 1
∴ A's share = (800 × 3/4) Tk = 600 Tk
