The research study is an eye opener and attempts to acquaint us with the problems of poor nations.
ব্যাখ্যা
Correct Sentence: The research study is an eye opener and attempts at acquainting us with the problems of poor nations.
Attempts can be followed by at (and a gerund) if attempts is a noun. Note that it can also use to and the infinitive form of the verb.
I made several attempts at doing that.
If attempts is a verb, it must be followed by to and an infinitive.
It attempts to do that.
If the sentence is lengthened, then attempts can be made into a noun, but an additional comma helps:
The research study is an eye-opener, and attempts at acquainting us with the problems of poor nations are ultimately successful.

Did you get what the teacher was saying?
ব্যাখ্যা
The meaning of the word 'get' changes with the context of the sentence.
Here, the teacher is saying something to the listener of this question, and the speaker is asking if they could comprehend what the teacher was saying.
'Get' is used informally here, and the best option that can explain it is the word 'understand' because it means 'to perceive the meaning of or comprehend', which means the same as 'get' in the sentence.
Hence option D is correct. From the other options, 'know' means 'to be aware or have knowledge of', it does not mean the same as 'get' because 'know' is used when the person is already aware of what is being said, whereas 'get' here does not suggest that.
Hence option A is incorrect. To receive is to acquire possession of something, like a gift, a title, or any information. The context of this sentence does not mean that the teacher is giving something that is to be acquired, but it is ought to be comprehended, hence option B is incorrect. To recognize means to identify something that you have previously seen or known. It is not synonymous with 'get' and hence option C is incorrect.

A passage is given with 3 questions:
Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce, explains lead author Yoshan Moodley, Professor at the Department of Zoology, University of Venda in South Africa.
Two centuries ago, the black rhinoceros – which roamed much of sub Saharan Africa – had 64 different genetic lineages; but today only 20 of these lineages remain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the 'genetic erosion' coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.

A car traveling with 5/7 of its actual speed covers 42 km in 1 hr 40 min 48 sec. What is the actual speed of the car?
ব্যাখ্যা
time = 1 hr 40 min 48 sec
= 1 hr + 40/60 hr + 48/3600 hr
= 1 + 2/3 + 1/75 = 126/75 hr
distance = 42 km
speed = distance/time = 42/( 126/75 ) = (42 × 75)/126 = 25 km/hr
⇒ 5/7 of the actual speed = 25
⇒ Actual speed = 25 × 7/5 = 35 km/hr
১৭.
A man travelled a distance of 61km in 9 hours. He travelled partly on foot at 4 km/hr and partly on bicycle at 9 km/hr. What is the distance travelled on foot?
ব্যাখ্যা
Let the time in which he travelled on foot = x hr
Then the time in which he travelled on bicycle = (9 − x ) hr
distance = speed × time
⇒ 4 x + 9 (9 − x) = 61
⇒ 4 x + 81 − 9 x = 61
⇒ 5 x = 20
⇒ x = 4
Distance travelled on foot = 4x
= 4 × 4
= 16 km
১৮.
A is thrice as good as B at work. A is able to finish a job in 60 days less than B. They can finish the work in _____ days if they work together.
ব্যাখ্যা
If A completes a work in 1 day, B completes the same work in 3 days.
This means, difference is 2 days, if B completes the work in 3 days
Therefore, difference is 60 days, if B completes the work in 90 days
⇒ Amount of work B can do in 1 day = 1/90
Amount of work A can do in 1 day = 3 × 1/90 = 1/30
Amount of work A and B can together do in 1 day = 1/90 + 1 /30 = 4/90 = 2/45
Therefore, A and B together can do the work in 45/2 days = 22 (1/2) days
১৯.
The ratio between the speeds of two trains is 7 : 8 . If the second train runs 400 km in 4 hours, What is the speed of the first train?
ব্যাখ্যা
Let the speed of the trains be 7 x and 8 x respectively.
Speed of second train = 400 /4 = 100 km/hr
⇒ 8 x = 100
⇒ x = 100/8 = 12.5
Speed of the first train = 7x = 7 × 12.5
= 87.5 km/hr

A man's age is 125 % of what it was 10 years ago, but 83 (1/3 )% of what it will be after 10 years. What is his present age?
ব্যাখ্যা
The age before 10 years increased by 25 % in 10 years.
In other words, the age before 10 years would have increased by 100 % in 40 years.
That is, the age before 10 years is 40 years. Therefore, the present age is 50.

A work can be finished in 16 days by 20 women. The same work can be finished in 15 days by 16 men. The ratio between the efficiency of a man and a woman is -
ব্যাখ্যা
Work done by 20 women in 1 day = 1/16
Work done by 1 woman in 1 day = 1/(16 × 20)
Work done by 16 men in 1 day = 1/15
Work done by 1 man in 1 day = 1/(15 × 16)
Efficiency of a man : efficiency of a woman
= 1/(15 × 16) : 1/(16 × 20)
= 1/15 : 1/20
= 1/3 : 1/4
= 4 : 3
২২.
A father said to his son, ''I was as old as you are at the present at the time of your birth''. If the father's age is 38 years now, what was the son's age five years back?
ব্যাখ্যা
Fathers age when his son was born= son's present age
Fathers age when his son was born + son's present age = father's present age
Therefore, 2 (Son's present age) = 38
=> Son's present age = 19
=> Son's age five years back = 19 − 5 = 14

There are two examination rooms A and B. If 10 students are sent from A to B, then the number of students in each room is the same. If 20 candidates are sent from B to A, then the number of students in A is double the number of students in B. The number of students in room A is:
ব্যাখ্যা
Let the number of students in rooms A and B be x and y respectively.
Then, x - 10 = y + 10
Or, x - y = 20 .... (i)
And x + 20 = 2(y - 20)
Or, x - 2y = -60 .... (ii)
Solving (i) and (ii) we get: x = 100, y = 80.
The required answer A = 100.
২৪.
A man has some hens and cows. If the number of heads be 48 and the number of feet equals 140, then the number of hens will be:
ব্যাখ্যা
Let the number of hens be x and the number of cows be y.
Then, x + y = 48 .... (i)
and 2x + 4y = 140
x + 2y = 70 .... (ii)
Solving (i) and (ii) we get:
x = 26, y = 22.
The required answer = 26.
২৫.
One ball is picked up randomly from a bag containing 8 yellow, 7 blue and 6 black balls. What is the probability that it is neither yellow nor black?
ব্যাখ্যা
Total number of balls, n(S) = 8 + 7 + 6 = 21
n(E) = Number of ways in which a ball can be selected which is neither yellow nor black = 7 (∵ there are only 7 balls which are neither yellow nor black)
P(E) = n(E)/n(S) = 7/21 = 1/3
২৬.
A sum of money becomes 7/ 5 of itself in 4 years at a certain rate of simple interest. What is the rate of interest per annum?
ব্যাখ্যা
Let the sum be x
Amount after 4 years = 7x /5
SI for 4 years = 7x/ 5 − x = 2x/5
R = (100 × SI)/ PT
= (100 × 2 x /5)/( x × 4)
= 10
Alternative:
The sum makes 2 /5 of itself in 4 years.
That is , 40 % in 4 years. That is 10% each year.
Therefore, rate of interest per annum is 10%.
২৭.
What is the compound interest on a sum of tk 40, 000 for 3 years at the rate of 11% per annum?
ব্যাখ্যা
Amount after 3 years = 40000 {(1 + 11)/100}3
= 40000 ( 111 /100 )3
= 54705.24
Compound interest = 54705.24 − 40000
= 14705.24

The angle of elevation of a ladder leaning against a wall is 60° and the foot of the ladder is 4.6 m away from the wall. The length of the ladder is:
ব্যাখ্যা
Let AB be the wall and BC be the ladder
Then, ACB = 60°
and AC = 4.6 m.
AC/BC = cos 60° = 1/2
BC = 2 × AC = (2 × 4.6) m = 9.2 m.
Then, ACB = 60°
and AC = 4.6 m.
AC/BC = cos 60° = 1/2
BC = 2 × AC = (2 × 4.6) m = 9.2 m.

A and B started a partnership business investing some amount in the ratio of 3 : 5. C joined them after six months with an amount equal to that of B. In what proportion should the profit at the end of one year be distributed among A, B and C?
ব্যাখ্যা
Let the initial investments of A and B be 3x and 5x.
A : B : C = (3x × 12) : (5x × 12) : (5x × 6)
= 36 : 60 : 30
= 6 : 10 : 5.
A : B : C = (3x × 12) : (5x × 12) : (5x × 6)
= 36 : 60 : 30
= 6 : 10 : 5.

What is the greatest number of four digits which is divisible by 15, 25, 40 and 75 ?
ব্যাখ্যা
Greatest number of four digits = 9999
LCM of 15, 25, 40 and 75 = 600
9999 ÷ 600 = 16, remainder = 399
Hence, greatest number of four digits which is divisible by 15, 25, 40 and 75 = 9999 - 399 = 9600
