Answer: Option C

Explanation:

Based on the given information, let's analyze the options provided:

A. There are certain disadvantages for the United States economy attached to devaluation.
This can be inferred from the statement. If the dollar is devalued in terms of other currencies, it suggests that there may be certain disadvantages for the United States economy, such as potentially higher import costs and reduced purchasing power.

B. The prospect of devaluation results in a speculative outflow of funds.
This can be inferred from the statement. If there is a prospect of devaluation, it can lead to a speculative outflow of funds as individuals and investors anticipate a potential decrease in the value of the currency.

C. By encouraging exports and discouraging imports, devaluation can improve the American balance of payments.
This can be inferred from the statement. Devaluation can make American goods relatively cheaper in terms of foreign currencies, which can encourage exports and discourage imports. This shift in trade balance can potentially improve the American balance of payments.

D. The difference between the exports and imports is called the trade gap.
This is not directly stated or implied in the given information. The term "trade gap" refers to the difference between the value of a country's exports and imports, but the statement does not provide information about the trade gap.

E. It is possible that inflation neutralizes the beneficial effects of devaluation.
This can be inferred from the statement. If devaluation leads to higher prices for imported goods, it can contribute to inflation. Inflation can potentially offset the beneficial effects of devaluation by increasing domestic prices and reducing the competitiveness of American goods.

Therefore, the option that cannot be inferred from the statement is option D: The difference between the exports and imports is called the trade gap.

Answer: Option D

Explanation:

In a right-angled triangle, you can use the Pythagorean theorem to find the length of the third side if you know the lengths of the other two sides. The Pythagorean theorem states:

c² = a² + b²

Where:

c is the length of the hypotenuse (the third side).
a and b are the lengths of the other two sides.
In this case, a = 5 cm and b = 12 cm. We want to find c:

c² = 5² + 12² c² = 25 + 144 c² = 169

Now, take the square root of both sides to find c:

c = √169 c = 13 cm

So, the length of the third side (the hypotenuse) is 13 cm.

411 . The lengths of the sides of a triangle are in the ratio of 3 to 5 to 6 . If the perimeter of the triangle is 70, what is the length of the longest side ?

A. 5
B. 6
C. 15
D. 30

View Answer	Favorite Question

Answer: Option D

Explanation:

Let the sides of the triangle are

3x,5x and 6x

Given perimeter(3x + 5x + 6x) = 70

= > 14x = 70

∴ x = 5

So longest side of the triangle is 6

= 6×5 = 30

C. Tk. 3840
D. None of these

View Answer	Favorite Question

Answer: Option D

Explanation:

Assume the cost of Table and Chair is Tk. X and Tk. Y
Write the Equation for the Question:
•The price of 10 chairs is equal to that of 4 tables
10X = 4Y
Y = 5x/2
•The price of 15 chairs and 2 tables together is Tk. 4000.
15X + 2*Y = 4000
15X + 2*5x/2 = 4000
20X = 4000
X = 200
•Substitute X value in Equation.
So, Y = (5/2*200)
Y = 500
•The total price of 12 chairs and 3 tables is,
12X + 3Y = 12*200 + 3*500
= 2400 + 1500
= 3900
The total price of 12 chairs and 3 tables is 3900 Taka.
