View Answer	Favorite Question

Answer: Option B

Explanation:

He sold his watch at loss of 5%. If he sells his watch for Rs. 56.25 more, he would gain 10%. It means that15% = Tk. 56.25.
So,1% = 56.2515
100% = 56.25 × 10015
= Tk. 375
Therefore, the cost price of the watch is Tk. 375

Answer: Option D

Explanation:

প্রশ্নে বলা হচ্ছে - এক লোক তার আয়ের 75% ব্যয় করেন। তার আয় 20% বেড়ে গেল এবং ব্যয় বেড়ে গেল 15% একন তার সঞ্চয় শতকরা ক বাড়বে?

ধরি লোকটি আয় = 100 টাকা

অতএব, লোকটির ব্যয় = 75 টাকা এবং সঞ্চয় থাকে

= 100 - 75 = 25 টাকা

20% বৃদ্ধিতে নতুন আয় = 100 + 20 = 120 টাকা

15% বৃদ্ধিতে নতুন ব্যয় = 75 + 75 এর 15%

= 75 + (75×15)/100 = 86.25 টাকা

অতএব, সঞ্চয় বাড়ে = 120 - 86.258 = 33.75 টাকা

অতএব, শতকরা, = {(33.75 - 25/25) × 100} %

{(8.75/75) × 100} % = 35%

Explanation:

969 . A man travels 100 miles at 20 miles per, 60 miles at 30 miles per hour and and 80 miles at 10 miles per hour, what is his average rate for the three trips?

A. 18 miles per hour
B. 17 miles per hour
C. 20 miles per hour
D. 16 miles per hour

View Answer	Favorite Question

Answer: Option D

Explanation:

Time travelled at 20 miles//hr = 100/20 = 5 hrs

Time travelled at 30 miles//hr = 60/30 = 2 hrs

Time travelled at 10 miles//hr = 80/10 = 8 hrs

Total time travelled = 5 + 2 + 8 = 15 hrs

Total travelled = 100 + 60 + 80 = 240 miles

Average rate = 240 / 15 = 16 miles per hour

Bangladesh Bank - Assistant Director - 2006

D. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

To calculate the average speed of a man who travels a certain distance at a rate of 20 miles an hour and returns at the rate of 30 miles an hour, we can use the following formula:

Average speed = 2 * (Distance traveled) / (Total time taken)

We know that the distance traveled in both directions is the same. Let the distance traveled be d miles.

The total time taken is equal to the time taken to travel d miles at a rate of 20 miles an hour plus the time taken to travel d miles at a rate of 30 miles an hour.

Total time taken = d / 20 + d / 30 = 5d / 60 hours

Substituting the given values in the formula for average speed, we get:

Average speed = 2 * d / (5d / 60) = 24 miles per hour

Therefore, the average speed of the man is 24 miles per hour.

So the answer is 24

Explanation:

973 . A man walked 2 km east, then 2 km south, then again 4 km east and finally 10 km north. How far in a straight line did he walk from the starting point ?

A. 10
B. 9
C. 8
D. 7

View Answer	Favorite Question

Answer: Option A

Explanation:

Let's visualize this situation step by step:

The man walked 2 km east.
Then, he walked 2 km south.
Next, he walked 4 km east.
Finally, he walked 10 km north.
To find the straight-line distance from the starting point, we can treat this as a displacement problem. We can use the Pythagorean theorem because the man's path forms a right-angled triangle.

The 2 km east and 4 km east segments form the horizontal legs of the right triangle.
The 2 km south and 10 km north segments form the vertical legs of the right triangle.
Let's calculate the lengths of these legs separately:

Horizontal leg (East): 2 km + 4 km = 6 km

Vertical leg (North-South): 10 km (north) - 2 km (south) = 8 km (net northward)

Now, we can use the Pythagorean theorem to find the length of the hypotenuse (the straight-line distance):

c^2=a^2+b^2

Where:

c is the length of the hypotenuse (the straight-line distance).
a is the horizontal leg (6 km).
b is the vertical leg (8 km).
Substitute the values:

c^2=6^2+8^2

c^2=36+64

c^2=100

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

c=100=10 kilometers

So, the straight-line distance from the starting point is 10 kilometers. The correct answer is indeed 10, as provided in the answer choices.
