Questions (21-30): Read the following questions carefully and choose the right
21. Alam sold two vehicles for Tk. 46000 each. If he gained 10% on the first and lost 10% on another. then what is his percentage profit or loss in this transaction?
(A) 2% loss
(B) 1% profit
(C) 1% loss
(D) None of these
Answer: (C) 1% loss
Solution:
Let, the profit be X% and loss be Y% .
So,
Net profit or loss% = X +(-Y) + X×(-Y)/100
(Negative sign denotes that their is a loss)
Their is 10% loss and 10% profit then
Net profit or loss% = 10+(-10)+10×(-10)/100 =10–10–100/100 = 0–1 = -1
( negative sign here shows that there is a net loss )
So the net loss percentage is 1% .
22. A square is inscribed in a circle of diameter 2a and another square is circumscribing circle. The difference between the areas of outer and inner squares is
(A) a2
(B) 2a2
(C) 3a2
(D) 4a2
Answer: (B) 2a2
Solution:
Area or outer square = 2a x 2a = 4a2
In △BAD
(BD)2=(AD)2+(AB)2
⇒ (2a)2=x2+x2
⇒ 4a2=2×2
⇒ 2a2=x2
∴ x=√2a.
Area of inner square =√2a x √2a=2a2
∴ Difference between the areas of the outer and inner square =4a2−2a2=2a2
23. 12 marbles are selected at random from a large collection of white, red, green and yellow marbles. The number of marbles of each color is unlimited. Find the probability that the selection contains at least one marble of each color?
(A) 34/91
(B) 23/91
(C) 36/91
(D) 33/91
Answer: (D) 33/91
SOlution:
Given, W+R+G+Y=12, where all are positive integers.
first, give one to each, hence 4 gone. Now you can distribute the remaining 8 to anyone as the restriction of at least one is done.. W+R+G+Y=8..W+R+G+Y=8.. Now, take this as 8 marbles and 3 partitions, so total 11 things. You can choose these 3 partitions in 11C3 ways=11!/8!3!=11∗10∗9/3∗2=11∗5∗3 Step II..
Total ways..
W+R+G+Y=12
Now, take this as 12 marbles and 3 partitions, so total 15 things. You can choose these 3 partitions in 15C3 ways=15!/12!3!=15∗14∗13/3∗2=5∗7∗13
Probability = 11∗5∗3/5∗7∗13=33/91
24. A motor-cycle covers 40 km with a speed of 20 km/hr. Find the speed of the motorcycle for the next 40 km journey so that the average speed of the whole journey will be 30 km/hr.
(A) 70.0 km/hr
(B) 52.5 km/hr
(C) 60.0 km/hr
(D) 60.5 km/hr
Answer: (C) 60.0 km/hr
Solution:
Let, speed of the motorcycle for the next 40 km = x km/hr
Average speed,
30 = 2.x.20/(20+x)
Or, 600 + 30x = 40x
∴ x = 60
25. A man can row 6 km/hr in still water. If the speed of the current is 2 km/hr, it takes 3 hours more in upstream than in the downstream for the same distance. The distance is
(A) 30 km
(B) 24 km
(C) 20 km
(D) 32 km
Answer: (B) 24 km
Solution:
Let, d be the distance.
Then,
d/(6–2)kph = d/(6+2)kph +3
Or, d/4 = d/8 +3
Or, d/8 =3
∴ d=24 km distance
26. The respective ratio between the speed of a car, a train, and a bus is 5:9:4. The average speed of the car, bus and train is 72 km/hr together. What is the average speed of the car and the train together?
(A) 82 km/hr
(B) 72 km/hr
(C) 67 km/hr
(D) 84 km/hr
Answer: (D) 84 km/hr
Solution:
5x + 9x + 4x = 72 × 3
Or, 18x = 72 × 3
∴ x = 12
Avg. speed of the car and the train,
= (5x+9x)/2 = 7x = 7X12 = 84 km/hr
27. Three angles of a triangle are in proportion 5:6:7. Then what is the difference in degrees between the biggest and the smallest angles?
(A) 20°
(B) 10°
(C) 30°
(D) 25°
Answer: (A) 20°
Solution:
5x°+6x°+7x°=180°
Or, 18x°=180°
∴ x=10°
Largest angle =7x° = 7(10)°= 70°
Smallest Angle
5x°=5(10)°=50°
∴ Difference = 70° – 50° = 20°
28. A water tank has two taps (Tap-1 and Tap-2). Tap-I can fill a tank in 8 hours and Tap-2 can empty the tank in 16 hours. How long will they take to fill the tank if both taps are opened simultaneously but Tap-2 is closed after 8 hours?
(A) 10
(B) 12
(C) 14
(D) 16
Answer: (B) 12
Solution:
Tap-1, fills in 1 hr = 1/8
Tap-2, empties in 1 hr = 1/16
When both taps are open, the tank fills in 1 hr = (1/8 – 1/16) = 1/16
In 8 hrs, the tank fills = 1/16 ×৪ = ½
Remaining = 1 – ½ = ½
½ is filled by only Tap 1
1/8 is filled by Tap-1 in 1 hr
So, ½ is filled by = (1×8)/2= 4 hr
Total time = 8+4 = 12 hr
29. The average of the three numbers x, y and z is 45. x is greater than the average of y and z by 9. The average of y and z is greater than y by 2. Then the difference of x and z is
(A) 3
(B) 5
(C) 7
(D) 11
Answer: (C) 7
Solution:
(x+y+z)/3 = 45
Or, x+y+z=135——(1)
Again,
X=(y+z)/2 + 9
Or, 2x-y-z = 18 ——(2)
From (1) + (2),
3x = 153
Or, x = 51
Again,
(y+z)/2= y+2
Or, y = z-4
From (1)
x+y+z=135
Or, 51+z-4+z=135
Or, z = 40
So, x-z = 51-44 = 7
