সঠিক উত্তর
3 (1150 gms)
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,
65 + 10x = 155
⇒ 10x = 90
∴ x = 9
∴ The additional weight 100 × 9 = 100 × 9 = 900 grams
∴ Total weight will be 900 + 250 = 1150 gms
