সঠিক উত্তর
1 (1000 grams)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Let the additional is 100x grams
Additional 100 grams requires Tk.10
∴ Additional 100x grams requires Tk. (10 × 100x)/100 = Tk. 10x
ATQ,
95 + 10x = 165
⇒ 10x = 70
∴ x = 7
∴ The additional weight = 100 × 7 = 700 grams
∴ Total weight will be = 700 + 300 = 1000 grams
