Answer: Option B

Explanation:

25 %লাভে A এর বিক্রয়মূল্য ( 120 + 120 × 25/100) টাকা = 150 টাকা।

B এর ক্রয়মূল্য = 150 টাকা।

10% লাভে,

C এর বিক্রয়মূল্য 110 টাকা হলে ক্রয়মূল্য 100 টাকা

C এর বিক্রয়মূল্য 198 টাকা হলে ক্রয়মূল্য ( 100 × 198 /110) = 180 টাকা।

B এর বিক্রয়মূল্য 180 টাকা।

B এর লাভের হার = ( 180 - 150 /150 × 100) % = ( 30/150 × 100) % = 20%

Answer: Option A

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 C

Explanation:

Let's assume that the man bought x eggs.

Since 10% of the eggs are rotten, the number of good eggs he has is 90% of x, which is 0.9x.

Now, he gives away 80% of the remainder (i.e., 100% - 10% = 90%) to his neighbors, which means he is left with 20% of the remainder. This can be expressed as:

0.2(0.9x) = 36

Simplifying this equation, we get:

0.18x = 36

x = 200

Therefore, the man bought 200 eggs.
