Let at present,
Woman's age be x
and her son's age be y
Then, A/Q,
x=30y ................................................. (1)
18 years later,
Woman's age = x+18
her son's age= y+18
Now, A/Q,
x+18=3*(y+18)
or, x+18=3y+54
or, x-3y=54-18
or, x-3y= 36
or, 30y - 3y = 36 [From eq (1)]
or, 27y = 36
or, y = 36/27 = 12/9 = 4/3
So, y= 4/3
Then, x= 30*4/3 = 40 years

X men can do the work in 8 days
1 man can do the work in 8*x days
Again,
X+4 men can do the work in 6 days
1 man can do the work in 6*(X+4) days.
Now, A/Q,
8X = 6*(X+4)
Or, 8X = 6X+24
Or, 8X-6X=24
Or, 2X= 24
Or, X= 12

Let marks of Karim's Mathematics be = m
And, marks of Karim's Social Studies be = s
Then, A/Q,
m/3 - s/2 = 30
(2m - 3s)/6 = 30
2m - 3s = 180 .................. (1)
And, we know that, m+s = 240 ............... (2)
multipying (2) with 2, we get,
2m + 2s = 480 ................. (3)
From (3) - (1), we get,
2m + 2s - 2m +3s = 480 + 180
5s = 660
s = 660/5 = 132

Payment without the registration fee = 1300 - 50 = 1250 tk
Now, Total Cost of first 3 days = 3*50 = 150 tk
Total Cost of next 5 days = 5*100 = 500 tk
Thus, Total cost of first 8 days = 500+150 = 650 tk
We can see that the person surely stayed at least 8 days.
Remaider of the payment is = (1250-650) = 600 tk
Now, Afterward each day costs 300 tk.
Thus, with the remainder of money person could stay = (600/300) days
= 2 days
Thus, Total days of the person's stay = 8 + 2 = 10

We know that, Speed = Distance/Time taken
Thus, Time taken = Distance/Speed
While Travelling,
Time taken = 150/50 = 3 hours
While Returning,
Time taken = 150/30 = 5 hours
Total time taken during the journey = 3 + 5 hours = 8 hours
And, Total distance covered during the journey
= (150 + 150) km
= 300 km
Thus Speed = 300/8 = 37.5 km/h

4/x + 3/5 = 10/x
or, (20 + 3x)/5x = 10/x
or, 20x + 3x2 = 50x
or, 3x2 - 50x + 20x = 0
or, 3x2 - 30x = 0
or, 3x(x – 10) = 0
Now,
Either,
3x = 0
x = 0
Or,
x – 10 = 0
x = 10

If Rahim's Collection is X
Then, Amin's Collection is 0.8X
Now, A/Q,
X - 0.8X = 80
or, 0.2X = 80
or, X = 80/0.2 = 400
So, Rahim has 400 marbles
and Amin has 0.8*400 = 320 marbles
Together they have = 400+320 = 720 marbles
Q19. Passage Questions(71 to 75): Read the few paragraphs below and answer questions: Airbus says it has turned the corner after a crisis connected to production problems and turmoil in the boardrooms at its A380 super-jumbo project that has gone on for the past year. Speaking at the paris air show, Louis Galois, CEO of the European plane maker, said, “Airbus is back”. Airbus, which announced a raft of orders on the first day of the show, is competing with Boeing, its American rival, for the litle of the largest plane maker in the world. Boeing is expected to reveal the numbers of orders for its 787 Dream liner soon. Airbus orders unveiled on Monday included Qatar Airways confirming a $750m. Boeing and Airbus are also competing for orders from aircraft leasing firms. Orders from these companies who rank highly among the biggest global buyers of aircraft are often regarded as an indication of how successful a model will be in the long term. Airbus also secured orders from US Airways that are worth $10bn for 22 of its A350 jets. 60 A320s and ten of its A330-200 wide-body planes. A few months ago, Aribus unveiled a major cost-cutting program aiming to reduce the workforce in Europe by10,000, as well as announcing a group restructuring. “I can tell you with full confidence that Airbus is back and fully back, as you have started noting yesterday as demonstrated by our first day announcements, “said Mr. Gallois on the air show. However, Boeing also announced a deal with General Electric (GE) on the show’s first day. GE’s commercial aviation services placed an order for six 777 Boeing freighters valued at around $ 4bn. to be delivered in the last quarter of A wall Street Journal website report, quoting the Delta operating chief yesterday said that Delta Air Lines were on the verge of ordering as many as 125 Boeing 787 jetliners by the end of his year. However, a spokesman for Delta later said that it had been having conversations “With several aircraft makers” said that “no final decision” had been made on future fleet purchases. (Q-75): Boeing
