প্রশ্নঃ An employer pays 3 workers X, Y, and Z a total of Tk. 36,600.00 a week. X's paid 125% of the amount Y is paid and 80% of the amount Z is paid. How much does X make a week?

বর্ণনাঃ

X = 125/100 of Y    or,  Y = 100X/125 = 4X/5

Again,  X = 80/100 of  Z    or,  Z = 100X/80 =5X/4

Now,  X + Y + Z = 36600

or,  X + 4X/5 + 5X/4 = 36600

or,  (20X + 16X + 25X) / 20 = 36600

or,  61X = 20 x 36600

So,  X = 12000 TK.

প্রশ্নঃ A Company makes a profit 6% on its first Tk. 10,000 of sales day and 5% an all sales in excess of Tk. 10,000 for that day. How much profit will the company make in a day when sales are Tk. 16,000?

বর্ণনাঃ

Profit on first 10,000Tk. = 6*10000/100 = 600 Tk.

Profit on the rest of 60,000 Tk. that is,

Profit on 50,000 Tk. = 5*50000/100 = 2500 Tk.

Total Profit = ( 2500 + 600 ) Tk. = 3100 Tk.

প্রশ্নঃ If 18 identical machines required 40 days to complete a job, how many fewer days would have been required to do the job if 6 additional machines of the same type had been used from the beginning?

বর্ণনাঃ

18 machines complete a job in 40 days

So, 18+6 = 24 machines complete the job in 40 x 18 / 24 = 30 days

Number of days saved = 40 - 30 = 10 days

প্রশ্নঃ If 4 is subtracted from one-fourth of a number, the result in 20. Which of the following is the number ---

বর্ণনাঃ

or,   X = 24 x 4 = 96

প্রশ্নঃ The area of a rectangle R with width 4 feet is equal to the area of a square S which has a perimeter of 24 feet. The perimeter of the rectangle R, in feet is :

বর্ণনাঃ

Side of the square = 24/4 = 6.

Area of the square = 6² = 36

ATQ, Area of rectangle, Length x width = 36

or,   Length x 4 = 36

or, Length = 9

So, the perimeter of the rectangle = 2(Length + width) = 2(9 + 4) = 26

প্রশ্নঃ Salma's average in four tests is 80%. What marks does she need in her fifth test to raise her average to 84%?

বর্ণনাঃ

Let the required score in the fifth test be X.

or,  320 + X = 5 x 84

or,  X = 420 - 320

or,  X = 100%

প্রশ্নঃ How many of the positive integers less than 25 are 2 less than an integer multiple of 4?

বর্ণনাঃ

As the number is 2 less than an integer multiple of 4, we can write the generalised form of the number as 4k – 2, where k is a positive integer.

When k = 1, the number is 4 x 1 – 2 = 2

When k = 2, the number is 4 x 2 – 2 = 6

When k = 3, the number is 4 x 3 – 2 = 10

When k = 4, the number is 4 x 4 – 2 = 14

When k = 5, the number is 4 x 5 – 2 = 18

When k = 6, the number is 4 x 6 – 2 = 22

When k = 7, the number is 4 x 7 – 2 = 26, which is not possible as the number is less than 25

so six  integers

বর্ণনাঃ

The least common multiple of 5, 6 and 7 is 210. Twice of 210 is 420. So, a minimum number of 210 apples can be distributed among them while the largest number possible not exceeding 440 is 420.

প্রশ্নঃ A manufacturer of TV wants to make a profit of Tk. 300,000 on sale of 200 TV sets. It costs Tk. 10,000 each to make the first 100 TV sets and Tk. 7,500 each to make TV sets after the first 100 sets. What should be the selling price of each TV sets in Taka?

বর্ণনাঃ

200 TV set এর Total cost = (10,000 × 100) + (7,500 × 100) = TK. 17,50,000 

    Total selling price = Cost price + Profit  

                              = 17,50,000 + 3,00,000 

                              = Tk. 20,50,000 

   Selling price of each TV set = 2050000/200 

                                           = TK. 10,250 

প্রশ্নঃ If Taka 4,500 was invested in bonds of a corporation when the price per bond was Tk. 9.00 and Taka 3,000 was invested in bonds of another corporation when the price was Tk. 10.00 per bond, what was the average price of bonds purchased?

বর্ণনাঃ

Total investment = 4500 + 3000 = 7500 TK.

Number of Bonds = 4500/9 + 3000/10 = 800

Average price per bond = 7500 / 800 = 9.375 TK.

প্রশ্নঃ If Salam makes a box every 5 minutes and Kalam takes 7 minutes to make a box, what will be the ratio of the number of boxes produced by Salam to the number of boxes produced by Kalam if they work for 5 hours and 50 minutes?

বর্ণনাঃ

5 hrs 50 mins = 5 x 60 + 50 = 350 minutes

Salam makes = 350/5 = 70 boxes

Kalam makes = 350/7 = 50 boxes

Ratio = 70 : 50 = 7 : 5

প্রশ্নঃ One dozen of eggs and ten pounds of apples have the same price. If the price of a dozen of eggs rises by 10% and the price of apples goes up by 2%, how much more will it cost to buy a dozen eggs and ten pounds of apples?

বর্ণনাঃ

As same price

Let one dozen eggs=100

ten pounds of apples=100

So total amount 200

Eggs price rises 10%=100+10=110

Apples price rises 2%=100+2=102

Rises total amount 212

Just rises amount 12

So cost price will 12*100/200=6%

বর্ণনাঃ

If each share price is 90 tk 

than share number= 45000/90=500

 If each share price is 100 tk than share number= 30000/100=300

total share= 500+300=800

So, average cost = (45000+30000)/800 = 93.75 taka  

ans: 93.75 taka 

প্রশ্নঃ In a class of 120 students. 60 percent can speak French and the rest can speak English only. If 25 percent of those in the class who can speak French can also speak English, how many of the students in the class can speak English?

বর্ণনাঃ

We notice that 120 x 0.6 = 72 students speak French

and 120 - 72 = 48 students speak only English.

Among the 72 students who speak French, 72 x 0.25 = 18 students speak English as well.

Therefore, 48 + 18 = 66 students can speak English.

প্রশ্নঃ A man has to go 10 km to catch a bus. He walks part of the way at 7 km/hr and runs the rest of the way at 12 km/hr. If he takes 1 hour 15 minutes to complete his journey, find how far he walked.

বর্ণনাঃ

let he walks for t hrs and runs for s hous

ATQ,

t + s = 1.25 hrs

and 

7t + 12s = 10

= >  7(1.25 -s) + 12s = 10

=> 8.75 - 7s + 12s = 10

=> 5s = 1.25

= > s = 0.25 hr

so, t= 1hr 

given tjhat, he walks 7 km in a hour

hence, he walks 7 km
