  1. 60 men could complete a piece of work in 250 days. They worked together for 200 days. After that the work had to be stopped for 10 day due to bad weather. How many more men should be engaged to complete the work in time?

Solution:

60 men work for 200 days.

They stops for 10 day due to bad weather.

So the work is to complete in

(250−200-10)=40 days in order to complete in schedule time i.e 250 days.

Let ‘n’ number of more man is required

(60men×200days)+(60+n)men×40days =60men×250days

Or, 12000+(60+n)men×40days =15000

Or, (60+n)40=3000

Or, 60+n=75

Or, n=15

  1. The ratio of the numbers of boys and girls in a school was 5: 3. Some new boys and girls were admitted to the school, in the ratio 5:7. At this, the total number of students in the school became 1200, and the ratio of boys to girls changed to 7:5. What was the number of students in the school before new admissions?

Solution:

Let,

Number of boys before new admission =5x

Number of girls before new admission =3x

So, total number of students = 5x + 3x = 8x

Some new boys and girls were admitted to the school, in the ratio 5:7.

So, Number of new boys =5y and Number of girls boys =7y

So, total number of new students = 5y + 7y = 12y

ATQ,

8x + 12y = 1200

Or, 2x + 3y = 300 —-(1)

Again,

(5x+5y) / (3x + 7y) = 7/5

Or, 25x + 25y = 21x + 49y

Or, 4x – 24y = 0

Or, 4x = 24y

Or, x = 6y

From (1),

2x + 3y = 300

Or, 2× 6y + 3y = 300

Or, 15y = 300

Or, y = 20

So, x = 20×6 = 120

Now, total number of students were 8x = 8×120 = 960

  1. An article manufactured by a company consists of two parts A and B. In the process of manufacture of part A, 9 out of 100 are likely to be defective. Similarly, 5 out of 100 are likely to be defective in the process of manufacture of part B. What will be the probability that the assembled part will not be defective?

Solution:

Probability that the article will be defective

=9/100 × 95/100 + 91/100 × 5/100 + 9/100 × 5/100

= 171/2000 + 91/2000 + 9/2000

= 271/2000

Therefore, Probability that the article will be non-defective

= 1 – 271/2000

= 1729/2000

=0.86

  1. Three runners A, B and C run a race, with runner A finishing 12 m ahead of runner B and 18 m ahead of runner C, in another race of same type runner B finished 8 m ahead of runner C. Each runner travels the entire distance at a constant speed. Find the length of the race.

Solution:

Let,

A finishes x m which is the required distance.

ATQ,

B finishes in (x-12) m

C finishes in (x-14) m

Again,

If B finishes in x m, then C finishes in (x-8) m

So,

A/B = x/(x-12); A/C = x/(x-18)

So, B/C = (x-12)/(x-18)——(1)

B/C = x/(x-8) ——————–(2)

From (1) & (2),

(x-12)/(x-18) = x/(x-8)

Or, x2 – 18x = x2 – 20x + 96

Or, 2x = 96

Or, x = 48

length of the race is 48 m.

  1. ‘A’ began a small business with a certain amount of money. After four months from the start of the business. ‘B’ joined the business with an amount which was Tk 6000 less than ‘A’s initial investment. ‘C’ joined the business after seven months from the start of business with an amount which was Tk.2000 less than A’s initial investment. At the end of the year total investment repented was Tk. 142000. What will be A’s share in the profit, if B received Tk.8000 as profit share?

Solution:

Let,

Initial investment of A be tk. x

Total investment at the end of year

= 12x + 8 (x – 6000) + 5 (x – 2000)

= 12x + 8x + 5x – 48000 – 10000

= tk.(25x – 58000)

ATQ,

25x – 58000 = 142000

Or, 25x = 142000 + 58000

Or, 25x = 200000

Or, x = 8000

Ratio of profit sharing for A, B and C

= (12 x 8000) : (8 x 2000) : (5 x 6000)

= 96000 : 16000 : 30000

= 48 : 8 : 15

B’s share = tk.8000

A’s share = 8000 x (48/8) = 48000 tk.

Natural disasters as we all know are the consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region. There is basically no human control over the natural disaster. We cannot stop these natural disasters but what is in our hands is to be prepared for these. Also, there are a lot of ways through which we can minimize the damage caused due to these natural disasters. Traditionally, natural disasters have been seen as situations that create challenges and problems mainly of a humanitarian nature. There is no way to prevent or avert these natural disasters, though scientists do claim to have found the ways to predict these natural disasters at most of the times they have failed to predict natural disasters causing some serious destruction.

  1. Translation: Bangla to English আমাদের দেশে দারিদ্র একটি বড় সমস্যা। কিন্তু এই শােচনীয় অবস্থা যে প্রধানত আমাদের নিজেদের দ্বারাই সৃষ্ট , তা আমরা প্রায়ই বুঝতেই পারি না। অনেকেই কঠিন পরিশ্রম এবং লাভজনক ব্যবসার দ্বারা নিজেদের অবস্থার উন্নতি সাধন করতে চেষ্টা করে না। তাছাড়া নিজেদের দুরবস্থার জন্য তারা কেবল হা-হুতাশ করে এবং ভাগ্যকে অভিসম্পাত করে। এই জড়তা ও শ্রমবিমুখতা ঝেড়ে ফেলতে হবে। মানুষ নিজেই নিজের ভাগ্য নির্মাতা’-এই মহান বাক্য স্মরণে রেখে দৃঢ় পদক্ষেপে জীবনপথে অগ্রসর হলে দারিদ্র ও দুঃখ দূর হবে এবং সুখ ও শান্তি আমাদের চিরসঙ্গী হবে।

  1. Read the following passage and answer the questions below:[20]

Plastics form an important part of synthetics – plastics are also polymers. Since most plastics can be easily molded into any shape after heating, they are used for making a variety of objects of different shapes and sizes. Plastics are poor conductors of heat which makes them suitable for making handles of cooking vessels, for use in refrigerators, and for making containers in microwave ovens.

Plastics are also poor conductors of electricity and that is why they are used as covering materials in electrical appliances, cords and wiring. Plastics are insoluble in water and, therefore, used for making bottles, buckets and other containers. Most plastics are inflammable. However, they do not corrode or rust and so mostly used in homes and laboratories.

Despite many different uses of plastics, there are environmental and health hazards associated with their disposal. This is because plastics are non-biodegradable. Accumulation of plastics is considered a serious problem because most of the methods used to dispose them result in some type of damage to the environment. Though somewhere between 500 million to one trillion plastic bags are consumed worldwide each year, most plastic wastes end up littering roadside and form ugly dumps that harbor many disease causing organisms. Plastics dumped in water bodies pose a threat to aquatic life; plastics that get buried prevent rain water from seeping into the ground. This affects the growth of plants. When plastics are burnt, they produce toxic gases and smoke.

(a) How do the plastics affect the growth of the plants?

(b) What are the hazards associated with the disposal of plastics?

(c) What is produced when plastics are burnt?

(d) What does the word synthetic denote?

(e) What do you learn after reading the passage?
