Answer: Option C

Explanation:

Suppose,
number of 5 taka note = x
number of 2 taka note = (30 - x)
Here, 5x + 2(30 - x) = 120
⇒ 5x + 60 - 2x = 120
⇒3x = 60 .:. x = 20
So, total 5 taka note = 20

Answer: Option E

Explanation:

প্রশ্নমতে, 50000 টাকার অতিরিক্ত ক্ষতিপূরণ প্রদান করেছিল = 56,000 - 50,000 = 6,000 টাকা

এখন, 20% ক্ষতির সমমূল্য = 6,000 টাকা

100% ক্ষতির সমমূল্য = 100×600020">100×600020100×600020 = 30,000 টাকা

মোট ক্ষতির পরিমাণ = (50,000 + 30,000)

= 80,000 টাকা ।

Answer: Option D

Explanation:

3508=x×2×14100+(13,900−x)×2×11100

350800=28x+22(13,900−x)

Simplifying, we have:

350800=28x+305800−22x

6x=350800−305800

6x=45000

Solving for x, we have:

x=450006

x=7500

Hence, the amount invested in scheme A is. 7500.

Answer: Option C

Explanation:

Mr. X 1 বছরের জন্য 10,000 টাকার একটি Deposit certificate কিনল, যা 6 মাস পর 8%

হার চক্রবৃদ্ধি সুদ প্রদান করে । Mr. X মোট কত টাকা সুদ পাবে তা বের করতে হবে ।

এখানে, সুদাসল, c = ?; semi annually হওয়ায়, n = 2; সময় t = 1 বছর; আসল, p = 10,000 Tk.

সুদের হার, r = 8% = 81008100

আমরাজানি, = P(1 + rn)n×tP(1 + rn)n×t

= > c = 100(1 + 82×100)2×1100(1 + 82×100)2×1

= > c = 10,000(1 + 125)210,000(1 + 125)2

= > c = 10,000(2625)210,000(2625)2

= > c = 10,000×26×2625×2510,000×26×2625×25

= > c = 10,816.

অর্থাৎ তিনি মোট সুদ পাবেন = (c - p) Tk.

= (10,816 - 10,000) Tk. = 816 টাকা ।

Answer: Option B

Explanation:

Even if the percentage of his commission remains the same, his total commission will increase due to the increament of his salary.

Previous commission = 10% of 5000 = 500

New salary = 5000 + 10% of 5000 = 5000 + 500 = 5500

New commission = 10% of 5500 = 550

Increament of commission = (550 - 500) / 500 x 100% = 10%.

Answer: Option D

Explanation:

Original price:

2/3 of stock = 10000

1/3 of stock = 5000

Sale price:

2/3 doubled = 2*10000 = 20000

1/3 quintupled = 5*5000 = 25000

Total profit = Total selling price - Total purchase price of stock =

(20000 + 25000) - (10000 + 5000) = 45000 - 15000 = 30000 tk
