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%.

প্রশ্নঃ Rahim sells 60% of apples he had and throws away 15% of the remainder . Next day he sells 50% of the remainder and throws away the rest. What percent (in total) of his apples does Rahim throw ?
বর্ণনাঃ
Let total apple= x
At 1st day: Remaining apple=40% of x= .4x and throwing apple= .4x *15%= .06x
At 2nd day: Remaining apple=.4x-.06x= .34x and throwing apple= .34x *50%= .17x
So total throwing apple=.06x+.17x= .23 x, that menas 23% of total

প্রশ্নঃ Rahim has three times as much money as Karim has. If Rahim gives Karim TK.50 then Karim will have three times as much money as Rahim will have. How much money do they have together ?
বর্ণনাঃ
Case 1: Rahim has three times as much money as Karim has.
let, karim's money = x, so rahim's money= 3x
Case 2: If Rahim gives Karim TK.50 then Karim will have three times as much money as Rahim will have.
After the condition - Rahim gives Karim TK.50
Karim's money = x+50 & rahim's money = 3x-50
After the condition - Karim will have three times as much money as Rahim will have,
karim's maney = 3 * rahim's money
or, x+50= 3(3x-50)
or, x+50 = 9x-150
or, 8x = 200
so, x = 25
So, The money do they have together is: x+ 3x = 4x = 4*25 = 100

বর্ণনাঃ
Let, s=distance between Dhaka to Mymensingh.
t= time taken to travel from Mymensingh to Dhaka
V=velocity
We have s=vt
Hare s(distance) is constant

v×t=v1×t1
60t=40(t+1)
t=20
So s=60×20=120 mile
Ans. 120 mile

প্রশ্নঃ Two-fifths of the socks in box are , one-third is blue, and the rest are green. What is the ratio of the green socks to the blue socks?
বর্ণনাঃ
Red socks = 2/5 of total
Blue socks = 1/3 of total
Rest are green, so green socks
= 1-2/5+1/3
= 1- (6+5)/15
= 1- 11/15
= (15-11)/15
= 4/15 of total
Hence, ratio of green to blue socks
= 4/15 : 1/3
= 4 : 5
So, the correct answer choice is option 1

বর্ণনাঃ
Faruk can do a work in 12 days and Salam can do the same work in 8 days. If Faruk , Salam and Babu work together , they can complete the work in 4 days . How many days will it take Babu to complete the work alone ?
in 1 day faruk can do 1/12 unit of work
in 1 day salma can do 1/8 unit of work
let asssume,
i 1 day babu can do 1/x unit of work
in 1 day babu , faruk and salma can do = (1/12 + 1/8 + 1/x) = 5x+24/24x unit of work
given that, in 4 days they can complete 1 unit of work together
so in 1 day the can do 1/4 unit of work
hence , 5x+24/24x =1/4
20x+96=24x

প্রশ্নঃ Three business partners Q, R, and S, agree to divide their total profit for a certain year in the ratios 2 : 5 : 8, respectively. If Q's share was Tk. 4000, what was the total profit of the business partners for the year?
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
