প্রশ্নঃ A painter has painted one-third of a rectangular wall which is ten feet high. When he will paint another 75 square feet of that wall, he will have finished three-quarters of the job. What is the length (the horizontal dimension) of the wall?

বর্ণনাঃ

Given that hight of the wall is 10 m

Let Base of the wall is x m

Area of wall is 10x    sq m

Three-quarter =3/4

ATQ= According to the question

(3/4-1/3) part of wall =75 sq m

So, 1 part of wall = 180 sq m

Rectangular base of the wall is 180/10=18 m

Ans. 18 m

2. A class of 50 girls and 70 boys sponsored a party. If 40% of the girls and 50% of the boys attended the party, approximately what percent of the class attended?

  46

  44

 42

  40

প্রশ্নঃ A class of 50 girls and 70 boys sponsored a party. If 40% of the girls and 50% of the boys attended the party, approximately what percent of the class attended?

বর্ণনাঃ

First, we need to find out 40% of the 50 girls. That is 50 x 0.4 = 20 girls.

Next, we need to find out 50% of the 70 boys. That is 70 x 0.5 = 35 boys.

Therefore, 20 + 35 = 55 people attended.

In total there were 50 + 70 = 120 people.

So the percent would be 55/120 = 11/24 ≈ 45.83% ≈ 46%.

3. If n is an integer between 0 and 100, then any of the following could (3n+3) except ---

  63

  208

 297

  300

প্রশ্নঃ If n is an integer between 0 and 100, then any of the following could (3n+3) except ---

বর্ণনাঃ

63=3*20+3; N=20
297=3*98+3; N=98

300=3*99+3; N=99

208=3*69+1 Not (3n+3)

4. If mx+ny=12my, then x/y+n/m= ?

  12m + 12y

  0

 12

  12mn

প্রশ্নঃ If mx+ny=12my, then x/y+n/m= ?

বর্ণনাঃ

mx+ny=12my

mx+ny/my=12

mx/my + ny/ my =12

x/y + n/m =12

এখানে,   ১২ কে ফ্রি করার জন্য my  দ্বারা উভয় পক্ষে ভাগ করে দেওয়া হয়েছে।   তারপরে mx ও my পাবে এবং  ny ও my পাবে তাই দুইটার নিচে দেওয়া হয়েছে এবং m আর m কাটে এবং y আর y কাটে।   আশা করি বুঝতে পারছেন

5. If x=3 and (x-y)2=4, then y could be ----

  0

  5

 -5

  1

প্রশ্নঃ If x=3 and (x-y)2=4, then y could be ----

বর্ণনাঃ

দেওয়া আছে, x=3

প্রদত্ত রাশি,   (x-y)2=4

                     (3-y)2=4  [ x  এর মান বসিয়ে]

                    6-2y=4

                    –2y=4-6

                   -2y=–2

                    y=–2/-2

                   y=1  আশা করি বুঝতে পারছেন

6. An item costs 90% of its original price. If Tk. 90 is added to the discount price, the cost of the item will be equal to its original price. What is the original price of the item?

  Tk. 900

  Tk. 990

 Tk. 9

  Tk. 90

প্রশ্নঃ An item costs 90% of its original price. If Tk. 90 is added to the discount price, the cost of the item will be equal to its original price. What is the original price of the item?

বর্ণনাঃ

Let original cost price is 100%

Item cost peice is  90%

Discount  =(100-90)%=10%

ATQ

10%=90

100%= 900

Ans. 900 TK

7. A sales representative will receive a 15% commission on a sale of Tk. 28,000. If she has already received Tk. 1500 as an advance of that commission, how much more is due on the commission?

  Tk. 2700

 Tk. 1200

  Tk. 4200

প্রশ্নঃ A sales representative will receive a 15% commission on a sale of Tk. 28,000. If she has already received Tk. 1500 as an advance of that commission, how much more is due on the commission?

বর্ণনাঃ

15% of 28000 Tk=(28000*15/100)=4200Tk

As she received 1500 Tk Commission  already, so she will receive more(4200-1500)=2700 Tk 

8. A merchant sells a radio for Tk. 80 and thereby makes a profit of 25% of the cost. What is the ratio of cost to selling price?

প্রশ্নঃ A merchant sells a radio for Tk. 80 and thereby makes a profit of 25% of the cost. What is the ratio of cost to selling price?

বর্ণনাঃ

at 25% profit, if cost price=100, then sell price=125

now, if sell price=80, then cost price=(100*80)/125  =64

so ratio=64/80=4:5

বর্ণনাঃ

If Q's share is 4,000tk and Q get 2x,

then 2x = 4000, x = 2000.

If R gets 5, then 5x = 10000.

If S gets 8, then 8x = 16000

Q + R + S = 4000 + 10000 + 16000 = 30000
