Answer: Option C

Explanation:

প্রশ্নে বলা হচ্ছে যে, একজন লোকের ১২০ দিনের জন্য কিছু টাকা প্রয়োজন । সে ব্যাংকের কাছে লোন চাইল । ব্যাংক তাকে ৬% হার ৩৬০ টাকা চার্জ করল । প্রশ্ন হলো সে ব্যাংক থেকে মোট কত টাকা নিয়েছিল ?

আমরা জানি, I = prt/100

এখানে,

I = সুদ/চার্জ = 360,

r = সুদের হার = 6% ,

t = সময় = 120 days = 120/30 মাস = 4 মাস = 4/12 বছর = 1/3 বছর

= > 360 = p×6×13100">p×6×13100

∴ p = 18,000

Answer: Option D

Explanation:

Let the cost price of clock A be ₹ x and that of clock B be ₹ (650 - x) From the given information, we can write 120 % of x = 75 % of (650 - x) Therefore, \frac{120}{100} \times x = \frac{75}{100} \times (650 - x) \Rightarrow x = \frac{75}{120} \times (650 - x) \Rightarrow x = \frac{5}{8} \times (650 - x) \Rightarrow 8 x = 3250 - 5 x \Rightarrow 8 x + 5 x = 3250 \Rightarrow 13 x = 3250 \Rightarrow x = \frac{3250}{13} \Rightarrow x = 250 Hence, the cost of clock A = ₹ 250 So, the cost of clock B = ₹ (650 - 250) = ₹ 400 Hence, the purchasing price of clock A is ₹ 250 and clock B is ₹ 400 .

Answer: Option A

Explanation:

ধরি নৌকা ও স্রোতের বেগ x ও y

স্রোতের প্রতিকূলে 90 মিনিট বা 3/2 ঘন্টায় যায় 3 মইল

স্রোতের প্রতিকূলে 1 ঘন্টায় যায় (3×2) / 3 মাইল = 2 মাইল

x - y = 2

x - 2 = 2 [ y = 2]

x = 4

স্রোতের প্রতিকূলে বেগ = x + y + 4 + 2 = 6

6 মাইল যায় 1 ঘন্টায়

3 মাইল যায় 3/6 ঘন্টায় = 1/2 ঘন্টায়

= 30 মিনিট
