In a garden, there are 10 rows and 12 columns of mango trees. The distance between two trees is 2 meters and a distance of one meter is left from all sides of the boundary of the garden. What is the length of the garden?

ক) 20 m খ) 22m গ) 24m ঘ) 26m

ব্যাখ্যা (Explanation)

Each row contains 12 plants.

There are 11 gapes between the two corner trees (11 x 2) metres and 1 metre on each side is left.

Therefore Length = (22 + 2) m = 24 m.

If x:y=5:3, then (8x-5y):(8x+5y)=?

ক) 3:12 খ) 8:13 গ) 3:11 ঘ) 5:11

ব্যাখ্যা (Explanation)

let x=5 and y=3

Then,

(8x-5y):(8x+5y)

= (8*5-5*3):(8*5+5*3)

= (40-15):(40+15)

= 25:55

= 5:11

A toy was bought for tk. 75 and sold at a gain 8%. What was its selling price in tk?

ক) 78 খ) 81 গ) 80 ঘ) 84

ব্যাখ্যা (Explanation)

When Buying price 100 tk, selling price 108 tk

When Buying price 75 tk, selling price 108*75/100 tk

= 81 tk

If a man’s salary is 20% more than that of his son, how many percent is the son’s salary if compared to the salary of his father?

ক) 75 খ) 80 গ) 83 ঘ) 85

ব্যাখ্যা (Explanation)

When son's salary is 100, that of father's is 120

Reversibly,

When father's salary is 120, that of son's is 100

and, When father's salary is 100, that of son's is 100*100/120

= 83.34 %

A woman is 30 times older than his son. 18 years later she will be thrice as old as her son. What is the woman’s present age in years?

ক) 30 খ) 35 গ) 36 ঘ) 40

ব্যাখ্যা (Explanation)

Let at present,

Woman's age be x

and her son's age be y

Then, A/Q,

x=30y ................................................. (1)

18 years later,

Woman's age = x+18

her son's age= y+18

Now, A/Q,

x+18=3*(y+18)

or, x+18=3y+54

or, x-3y=54-18

or, x-3y= 36

or, 30y - 3y = 36 [From eq (1)]

or, 27y = 36

or, y = 36/27 = 12/9 = 4/3

So, y= 4/3

Then, x= 30*4/3 = 40 years

If ‘X’ men can do a work in 8 days and “X+4” men can do it in 6 days , what is the value of “X”?

ক) 4 খ) 6 গ) 8 ঘ) 12

ব্যাখ্যা (Explanation)

X men can do the work in 8 days

1 man can do the work in 8*x days

Again,

X+4 men can do the work in 6 days

1 man can do the work in 6*(X+4) days.

Now, A/Q,

8X = 6*(X+4)

Or, 8X = 6X+24

Or, 8X-6X=24

Or, 2X= 24

Or, X= 12

If product of two sequential positive odd numbers is 255, what are those numbers?

ক) 11,13 খ) 13, 15 গ) 13, 17 ঘ) 15, 17

Go through the options. That is the fastest way

A third of Karim’s marks in Mathematics exceeds a half of his marks in social studies by 30, if Karim got 240 marks in the two subjects together, how many marks did he get in Social Studies?

ক) 88 খ) 98 গ) 132 ঘ) 122

ব্যাখ্যা (Explanation)

Let marks of Karim's Mathematics be = m

And, marks of Karim's Social Studies be = s

Then, A/Q,

m/3 - s/2 = 30

(2m - 3s)/6 = 30

2m - 3s = 180 .................. (1)

And, we know that, m+s = 240 ............... (2)

multipying (2) with 2, we get,

2m + 2s = 480 ................. (3)

From (3) - (1), we get,

2m + 2s - 2m +3s = 480 + 180

5s = 660

s = 660/5 = 132

The rent of a guest house was tk 50 per day for first three days tk 100 per day for next 5 days and tk 300 per day for other days. The registration fee in the beginning is tk If one has to pay tk1300, for how many days he availed of this facility?

ক) 10 খ) 12 গ) 15 ঘ) 8

ব্যাখ্যা (Explanation)

Payment without the registration fee = 1300 - 50 = 1250 tk

Now, Total Cost of first 3 days = 3*50 = 150 tk

Total Cost of next 5 days = 5*100 = 500 tk

Thus, Total cost of first 8 days = 500+150 = 650 tk

We can see that the person surely stayed at least 8 days.

Remaider of the payment is = (1250-650) = 600 tk

Now, Afterward each day costs 300 tk.

Thus, with the remainder of money person could stay = (600/300) days

= 2 days

Thus, Total days of the person's stay = 8 + 2 = 10

A motorist travels to a place 150 km away at an average speed of 50 km and returns at 30 km per hour. What is his average speed for the whole journey in km per hour?

ক) 35 খ) 37 গ) 37.5 ঘ) 40

ব্যাখ্যা (Explanation)

We know that, Speed = Distance/Time taken

Thus, Time taken = Distance/Speed

While Travelling,

Time taken = 150/50 = 3 hours

While Returning,

Time taken = 150/30 = 5 hours

Total time taken during the journey = 3 + 5 hours = 8 hours

And, Total distance covered during the journey

= (150 + 150) km

= 300 km

Thus Speed = 300/8 = 37.5 km/h

The average of Selim’s marks in 7 subject is His average in six subjects excluding science is How many marks did he get in Science?

ক) 72 খ) 90 গ) 93 ঘ) 98

In dividing a sum of money, the eldest of three brothers got 2/5^th of it and the youngest got tk. What was the total sum in tk, if the amount received by the other brother was 1/3^rd of the total?

ক) 98 খ) 450 গ) 480 ঘ) 110

ব্যাখ্যা (Explanation)

Let total amount be x

Then, A/Q,

x - 2x/5 - x/3 = 120

=> (15x - 6x - 5x)/15 = 120

=> 4x/15 = 120

=> x = 120*15/4 = 450

What is the value of x if 4/x + 3/5 = 10/x, then x=?

ক) 50 খ) 12 গ) 40 ঘ) 10

ব্যাখ্যা (Explanation)

4/x + 3/5 = 10/x

or, (20 + 3x)/5x = 10/x

or, 20x + 3x2 = 50x

or, 3x2 - 50x + 20x = 0

or, 3x2 - 30x = 0

or, 3x(x – 10) = 0

Now,

Either,

3x = 0

x = 0

Or,

x – 10 = 0

x = 10

If 3a+5b=10 and 5a + 3b=30, what is the average (arithmetic mean) of a and b?

ক) 4 খ) 2.5 গ) 2.5 ঘ) 4.5

ব্যাখ্যা (Explanation)

3a+5b=10 ..................... (1)

5a + 3b=30 ....................... (2)

We get from (1) + (2),

8a + 8b = 40

or, a + b = 5 (Dividing both sides by 8)

Now, The average would be,

(a + b)/2 = (5)/2 = 2.5

The number of marbles in Amin’s collection is 80% of the number in Rahim’s collection. If Rahim has 80 more marbles than Amin, how many marbles do they have altogether?

ক) 720 খ) 120 গ) 135 ঘ) 400

ব্যাখ্যা (Explanation)

If Rahim's Collection is X

Then, Amin's Collection is 0.8X

Now, A/Q,

X - 0.8X = 80

or, 0.2X = 80

or, X = 80/0.2 = 400

So, Rahim has 400 marbles

and Amin has 0.8*400 = 320 marbles

Together they have = 400+320 = 720 marbles

A water reservoir is 1/5^th full and requires 20 liters more to make it 3/5^th full. What is the capacity of the reservoir ( in liters)?

ক) 40 খ) 30 গ) 60 ঘ) 50

ব্যাখ্যা (Explanation)

Let full tank be X

Then, A/Q,

3X/5 - X/5 = 20

or, (3X - X) / 5 = 20

or, 2X/5 = 20

or, X = 20*5/2 = 100/2 = 50

What function does F1 stand for in most computers?

ক) Help খ) save গ) save as ঘ) cut-paste

Passage Questions(71 to 75): Read the few paragraphs below and answer questions: Airbus says it has turned the corner after a crisis connected to production problems and turmoil in the boardrooms at its A380 super-jumbo project that has gone on for the past year. Speaking at the paris air show, Louis Galois, CEO of the European plane maker, said, “Airbus is back”. Airbus, which announced a raft of orders on the first day of the show, is competing with Boeing, its American rival, for the litle of the largest plane maker in the world. Boeing is expected to reveal the numbers of orders for its 787 Dream liner soon. Airbus orders unveiled on Monday included Qatar Airways confirming a $750m. Boeing and Airbus are also competing for orders from aircraft leasing firms. Orders from these companies who rank highly among the biggest global buyers of aircraft are often regarded as an indication of how successful a model will be in the long term. Airbus also secured orders from US Airways that are worth $10bn for 22 of its A350 jets. 60 A320s and ten of its A330-200 wide-body planes. A few months ago, Aribus unveiled a major cost-cutting program aiming to reduce the workforce in Europe by10,000, as well as announcing a group restructuring. “I can tell you with full confidence that Airbus is back and fully back, as you have started noting yesterday as demonstrated by our first day announcements, “said Mr. Gallois on the air show. However, Boeing also announced a deal with General Electric (GE) on the show’s first day. GE’s commercial aviation services placed an order for six 777 Boeing freighters valued at around $ 4bn. to be delivered in the last quarter of A wall Street Journal website report, quoting the Delta operating chief yesterday said that Delta Air Lines were on the verge of ordering as many as 125 Boeing 787 jetliners by the end of his year. However, a spokesman for Delta later said that it had been having conversations “With several aircraft makers” said that “no final decision” had been made on future fleet purchases. (Q-75): Boeing
