Which one the following Operating System (OS) has command line as the user interface?

ক) DOS খ) Linux গ) Unix ঘ) All of these

The average of X and Y is 40, and the average of Y and Z is What is the value of(X-Z)?

ক) 5 খ) 10 গ) 15 ঘ) 20

ব্যাখ্যা (Explanation)

(X + Y) / 2 = 40

or, (X + Y) = 80

Again,

(Y + Z) / 2 = 35

or, (Y + Z) = 70

Now,

(X + Y) - (Y + Z) = 80 - 70

or, X - Z = 10

What is the rate of discount if a car that had a regular price of Tk. 30,00,000 is sold for Tk. 27,90,000?

ক) 7% খ) 8% গ) 9% ঘ) None of these

ব্যাখ্যা (Explanation)

Discount amount = 30,00,000 - 27,90,000 tk

= 2,10,000 tk

Thus,

When original price is 30,00,000, discount is 2,10,000 tk

When original price is 100, discount is 2,10,000 * 100 / 30,00,000 tk

= 7 tk

Zinat’s father contributes to his daughter’s saving by giving her 10% of her total saving. If Zinat saves Tk. 100 in June, Tk. 250 in july and Tk. 130 in August, how much will she have in savings (in Tk.) at the end of that time?

ক) 528 খ) 524 গ) 539 ঘ) 480

ব্যাখ্যা (Explanation)

Total savings in June = 100 + (100 * 10 / 100) tk = 110 tk

Total savings in July = 250 + (250 * 10 / 100) tk = 275 tk

Total savings in August = 130 + (130 * 10 / 100) tk = 143 tk

At the end of that time, she will have,

110 + 275 + 143 tk = 528 tk

In a triangle the lengths of two sides are 5 and 9 and the length of the third side is represented by x. Which statement is always true?

ক) x>5 খ) x<9 গ) 5≤ x ≤ 9 ঘ) 4<x <14

ব্যাখ্যা (Explanation)

If we let the side with length 9 as the largest side of the triangle, then 5 + x must be greater than 9 to form a triangle.

Thus, 5 + x > 9

or, x > 9 - 5

or, x > 4

If we let x be the largest side.

Then, x must be less than 5 + 9

So, x < 14

Thus, by combining it, we get,

4<x <14

When 4 is added to one half of a number, the result is What is the number?

ক) 10 খ) 15 গ) 20 ঘ) 25

ব্যাখ্যা (Explanation)

The number is x.

One half of the number is x /2

So, (x / 2) + 4 = 14

or, (x / 2) = 14 - 4 = 10

or, x = 10 * 2 = 20

If 4 times an integer x is increased by 10, the result is always greater than 18 and less than What is the least value of x?

ক) 2 খ) 3 গ) 5 ঘ) 4

ব্যাখ্যা (Explanation)

You have to go through the options here to find out the answer.

Option 1:

2*4 + 10 = 18

This is not greater than 18.

Option 2:

3*4 + 10 = 22

This is greater than 18 and less than 34.

Plus, this is the lowest integer that follows the given conditions.

What is the sum of 15, 10 and 65?

ক) 1/2 খ) 8/10 গ) 5/16 ঘ) 9/10

ব্যাখ্যা (Explanation)

0.65

+ 0.15

+ 0.10

---------------

= 0.90

= 90 /100

= 9 / 10

In his pocket a boy has 3 red marbles, 4 blue marbles and 4 green marbles. How many marbles will he have to take out of his pocket to ensure that he has taken out at least one of each color?

ক) 3 খ) 8 গ) 9 ঘ) 11

ব্যাখ্যা (Explanation)

The worst scenario would be that he has taken 4 blue and 4 green, total of 8 marbles, and still doesn't have 3 distinct colors. But the next draw (9th) will surely be the third color red as there is no other color marble left in pocket.

The electric company charges Tk 30 per kilowatt-hour (KWH). Rahim used 2800 KWH in April, 3200 KWH in May, and 3600 KWH in June. What was his average cost of electricity for the 3 months?

ক) Tk. 72 খ) Tk. 96 গ) Tk. 48 ঘ) Tk. 144

ব্যাখ্যা (Explanation)

For April,

Cost of electric bill = (2800 * 0.30) tk

= 840 tk

For May,

Cost of electric bill = (3200 * 0.30) tk

= 960 tk

For June,

Cost of electric bill = (3600 * 0.30) tk

= 1080 tk

Total Cost of 3 Months = (840 + 960 + 1080) tk

A ferry can carry 24 buses or 36 cars at a time. If there are 18 buses on the ferry, how many cars can be loaded onto it?

ক) 6 খ) 8 গ) 9 ঘ) 12

ব্যাখ্যা (Explanation)

24 buses = 36 cars

or, 1 bus = 36 / 24 cars = 3 /2 cars

Ferry is loaded with 18 buses. Ferry has free space in terms of buses = (24 - 18) buses

= 6 buses

Now,

1 bus = 3 /2 cars

6 buses = 3*6 / 2 cars

= 18 / 2 cars = 9 cars

If r = 5z and 15z = 3y, then r=?

ক) y খ) 2y গ) 5y ঘ) 10y

ব্যাখ্যা (Explanation)

3y= 15z Or, y= 5z = r

If the value of X and Y in the fractions XZ/Y are both tripled, how does the value of the fraction change?

ক) Increases by one third খ) triples গ) doubles ঘ) remains the same

ব্যাখ্যা (Explanation)

(xz)/y and (3xz)/(3y) (3xz)/(3y) = [(3)(xz)]/[(3)(y)] = [(3)/(3)][(xz)/y]

Which of the following fractions is the equivalent of 5%?

ক) 1/20 খ) 1/200 গ) 1/5000 ঘ) 1/2000

ব্যাখ্যা (Explanation)

To change percent into fraction, take out the percent symbol and divide it by 100. So, 0.5% becomes 0.5/100 Now, move the decimal place to the right in the numerator and the denominator until you have rid the fraction of decimals. So, 0.5/100 becomes 5/1000 The number of times you move the decimal place in the numerator is equal to the number of zeros you add in the denominator. Then reduce: 5/1000 = 1/200 (divide both numerator and denominator by common factor 5)

Jesmin spent one-third of her money on books and half of the remaining money on clothing. She then spent three-fourth of what she had left on food. She had 500 left over. How much money did she start with?

ক) Tk. 6000 খ) Tk. 8000 গ) Tk. 12000 ঘ) Tk. 1600

ব্যাখ্যা (Explanation)

Let us consider that she had x at the beginning.

She spent on books= x/3

Remainder after books purchase= (x - x/3)

She spent on clothing= (x - x/3) / 2

Remainder after cloth purchase = (x - x/3) / 2

She spent on food= 3[(x - x/3) / 2] / 4 = 3[(x - x/3) / 8] = (3x - x) / 8

= 2x / 8
