- A man can walk uphill at the rate of 2.5 km/hr and downhill at the rate of 3.25 km/hr. If the total time required walking a certain distance up the hill and return to the starting position is 4 hr 36 min, what is the distance he walked up the hill?

(A) 3.5 km

(B) 4.5 km

(C) 5.5 km

(D) 6.5 km

Answer: (D) 6.5 km

Exp:

Let the walked up at a distance of x km. then

x/2.5 + x/3.25 = 4 (36/60)

Or, (130x+100x)/325 = 23/5

Or, x = 6.5

- A, B and Center into a partnership with a certain capital in which A’s contribution is Tk. 10,000. If out of a total profit of Tk. 1,000. A gets Tk. 500, B gets Tk. 300 then C’s capital is

(A) Tk. 4000

(B) Tk. 3600

(C) Tk. 4800

(D) Tk. 4400

Answer: (A) Tk. 4000

Exp:

A : B : C = 500 : 300 : 200 = 5 : 3 : 2.

Let, their capitals be 5x, 3x and 2x respectively.

Then, 5x = 10000

Or, x = 2000.

C’s capital = 2x = 4000

- The marked price of an article is Tk.500. It is sold on two successive discounts of 20% and 10%. The selling price of that article is

(A) Tk. 350

(B) Tk.375

(C) Tk. 360

(D) Tk.400

Answer: (C) Tk. 360

Exp:

Two successive discount of 20% and 10% is equal to -20-10+(-20×-10)/100 =(-30+2)%=-28% single discount.

S.P. = 500× (100–28)/100 = 72×5=tk. 360

Answer:

- A vessel is filled with liquid, 3 parts of which are water and 5 parts syrup. How much of the mixture must be drawn off and replaced with water so that the mixture may be half water and half syrup?

(A) 1/3

(B) 1/4

(C) 1/5

(D) 1/7

Answer: (C) 1/5

Exp:

Suppose the vessel initially contains 8 litres of liquid.

Let, x litres of this liquid be replaced with water.

Quantity of water in new mixture =(3 -3x/8 + x) litres

Quantity of syrup in new mixture =(5 -5x/8) litres

So,

(3 -3x/8 + x) = (5 -5x/8)

Or, 5x + 24 = 40 – 5x

Or, 10x = 16

Or, x = 8/5

So, part of the mixture replaced =(8/5 × ¼) = 1/5

- One-fourth of the boys and three-eight of the girls in a school participated in the annual sports. What proportional part of the total student population of the school participated in the annual sports?

(A) 4/12

(B) 5/8

(C) 8/12

(D) None of these

Answer: (D) None of these

1/4 means, let total no. Of boys are 4 and out them 1 takes participate and

3/8 means , let total of girls are 8 and out of them 3 take participate

Now, total students in the school =(4+8)=12

And total students takes participate in annual sports =(1+3)= 4

It means, total 4 students take participate in sport out of 12 .

i.e 4/12 = 1/3

- If the rate of simple interest is 12% per annum the amount that would fetch interest of Tk. 6000 per annum is:

(A) TK. 50000

(B) TK. 7200

(C) Tk. 72000

(D) None of these

Answer: (A) TK. 50000

Exp:

R = 12%

I = 6000

Let,

P is the principal

SI= (P x R x T)/100

So,

6000=(P x 1 x 12)/100

Or,P =(6000 x 100)/12 = 50000

- The compound interest on a certain sum of money for 2 years at 10% per annum is tk. 420. The simple interest on the same sum at the same rate and for the same time will be?

(A) Tk. 350

(B) Tk. 375

(C) Tk 380

(D) TK. 400

Answer: (D) TK. 400

Let the sum be P.

So,

p(1+10/100)^{2}-p]=420

Or, 0.21p = 420

Or, p = 2000

SI = 2000×2×10/100 = 400

Possible outcomes = (RY, YP, PR)

(^{2}C_{1}× ^{4}C_{1} + ^{4}C_{1}× ^{6}C_{1} + ^{6}C_{1}× ^{2}C_{1 })

Required probability

= (^{2}C_{1}× ^{4}C_{1} + ^{4}C_{1}× ^{6}C_{1} + ^{6}C_{1}× ^{2}C_{1})/(^{12}C_{2})

= (8 + 24 + 12)/66

= 44/66

= 2/3

- The sum of the present ages of a father and his son is 60 years. Five years ago, father’s age was four times the age of the son. So now the son’s age will be

(A) 15 years

(B) 5 years

(C) 20 years

(D) 10 years

Answer: (A) 15 years

Let, the present ages of son and father be x and (60 -x) years respectively.

Then,

(60 – x) – 5 = 4(x – 5)

Or, 5x = 75

Or, x = 15

- A hall is 15 m long and 12 m broad. If the sum of the areas of the floor and the ceiling is equal to the sum of the areas of four walls, the volume of the hall is:

(A) 720 m

(B) 1200 m

(C) 900 m

(D) 1800 m

Answer: (B) 1200 m

Exp:

2(15 + 12) x h = 2(15 x 12)

Or, h =180/27 =20/3m.

Volume =(15 x 12 x 20/3)m^{3} = 1200 m^{3}

- A cylindrical rod of iron, whose height is equal to its radius, is melted and cast into spherical balls whose radius is half the radius of the rod. Find the number of balls.

(A) 2

(B) 3

(C) 4

(D) 6

Answer: (D) 6

Exp:

Volume of rod = πr^{2}h = πr^{2}×r = πr^{3}

Volume of one spherical ball =r/2

Volume of the spherical ball = {(4/3)πr^{3}} /8

Number of balls

=Volume of rod / volume of one ball

= πr^{3} /{(4/3)πr^{3}} /8

= πr^{3} × 8 × 3/4 πr^{3}

= 6

- A person’s present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?

(A) 36 years

(B) 38 years

(C) 40 years

(D) 42 years

Answer: (C) 40 years

Exp:

Let, the mother’s present age be x

So,

The person’s present age = 2x/5 yr

Now,

2x/5 + 8 = 1/2(x+8)

Or, x = 40

- The length of a rectangle is halved, while its breadth is tripled. What is the percentage change in area?

(A) 50% increase

(B) 25% increase

(C) 50% decrease

(D) 75% decrease

Answer: (A) 50% increase

Exp:

Let original length = x and

original breadth = y.

Original area = xy.

New length = x/2 and New breadth=3y

New area = (3/2) xy

So, Increase in area = (3/2)xy−xy=(1/2)xy

Increase % =[{(1/2)xy}/xy]×100=50%

- Fresh fruit contains 68% water and dry fruit contains 20% water. How much dry fruit can be obtained from 100 kg of fresh fruits?

(A) 20 kg

(B) 30 kg

(C) 35 kg

(D) 40 kg

Answer: (D) 40 kg

Exp:

As fresh fruit contain 68% of water 100 kilograms fresh fruits, will have 68 kg of water and hence 100 – 68 = 32 kg. of dried portion.

In dry fruits, we have 20% of water and hence dried portion is 100 – 20 = 80%

80 parts of dried portion makes 100 parts of dry fruits

and 1 part of dried portion makes 100/80 parts of dry fruits

and 32 kg of dried portion makes (100/80) × 32 kg. of dry fruits

= 40 kg. of dry fruits.

- A tap can fill a tank in 6 hours. After half the tank is filled, three more similar taps are opened. What is the total time taken to fill the tank completely?

(A) 3 hrs 15 min

(B) 3 hrs 45 min

(C) 4 hrs. 15 min

(D) None of these

Answer: (B) 3 hrs 45 min

Exp:

Time taken by one tap to fill half of the tank = 3 hrs.

Part filled by the four taps in 1 hour = (4 x1/6) =2/3

Remaining part = (1 -1/2) = ½

So,

2/3 : ½ :: 1:x

Or, x = (1/2 × 1 × 3/2) = ¾ hrs = 45 mins

So, total time taken = 3 hrs. 45 mins.

- The salaries of A, B, and are in the ratio of 1:2:3. The salary of B and C together is Tk 6000. By what percent is the salary of C more than that of A?

(A) 100%

(B) 150%

(C) 200%

(D) 250%

Answer: (C) 200%

Exp:

Let the salaries of A, B, C be x, 2x and 3x respectively.

Then,

2x + 3x = 6000

Or, x = 1200

A’s salary = tk. 1200, B’s salary = tk. 2400, and Cs salary tk. 3600

Excess of C’s salary over A’s= [(2400 /1200) × 100] = 200%

- Two numbers are in the ratio 3: 7. If 6 be added to each of them, then they are in the ratio 5:9. Find the numbers?

(A) 9 and 21

(B) 11 and 17

(C) 7 and 17

(D) 13 and 23

Answer: (A) 9 and 21

Exp:

Let, the two numbers be x and y

Given,

x : y = 3 : 7 …..(1)

Now,

x+6 : y+6 = 5 : 9 …..(2)

From (1), x = 3y/7

From (2), 5y – 9x = 24

Or, 5y – 9(3y/7) = 24

Or, y = 21

From (1), x = 9

Hence, the two numbers be 9 and 21

- 28√? +1426 = ¾ of 2872

(A) 576

(B) 1296

(C) 676

(D) 1444

Answer: (C) 676

Exp:

28√?= 3/4 of 2872-1426

Or, 28√? = 2154-1426

Or, 28√?= 728

Or, √?= 728/28= 104/4= 26

Or, ?= 26^{2}= 676

- A bag contains 50 P, 25 P and 10 P coins in the ratio 5: 9:4, amounting to Tk. 206. Find the number of coins of each type respectively.

(A) 360, 160, 200

(B) 160, 360,200

(C) 200,160,300

(D) 200, 360,160

Answer: (D) 200, 360,160

Exp:

Let, no of coins be 5x ,9x , 4x respectively

Now given total amount = tk. 206

So,

(.50)(5x) + (.25)(9x) + (.10)(4x) = 206

Or, x = 40

No. of 50p coins = 200

No. of 25p coins = 360

No. of 10p coins = 160

- Painter A can paint a house in 16 days, and painter B can do the same work in 20 days. With the help of painter C, they paint the house in 8 days only. Then, Painter C alone can do this task in

(A) 80 days

(B) 85 days

(C) 79 days

(D) 76 days

Answer: (A) 80 days

Exp:

A’s 1 day’s work = 1/16

B’s 1 day’s work = 1/20

(A + B + C)’s 1 day’s work = 1/10

C’s 1 day’s work = 1/10 – (1/16 + 1/20) = 1/80

So, C can paint the house in 80 days

- A and B start at the same time with speeds of 40 km/hr and 50 km/hr respectively. If in covering the journey A takes 15 minutes longer than B, the total distance of the journey is

(A) 46 km

(B) 48 km

(C) 50 km

(D) 52 km

Answer: (C) 50 km

Exp:

Let, distance of journey = x km

Time taken by A to Cover x km = x/40 hours.

Time taken by B to Cover x km = x/50 hours.

So,

x/40 – x/50 = 15/60

Or, x/200= 15/60

Or, x = (15 x 20)/6 = 50 km

- A person borrows Tk. 5000 for 2 years at 4% p.a. simple interest. He immediately lends it to another person at 6 (1/4)% per annum for 2 years. Find his gain in the transaction per year.

(A) Tk. 112.50

(B) Tk. 167.50

(C) Tk. 150

(D) Tk. 225

Answer: (A) Tk. 112.50

Exp:

Gain in 2 yrs = [(5000 × 25/4 × 2/100) – (5000 × 4 × 2/100)]= 225

So, gain in 1 yr = 225/2 = 112.50 tk.

- Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is:

(A) 1:3

(B) 3:2

(C) 3:4

(D) None of these

Answer: (B) 3:2

Exp:

Let,

Speeds of the two trains be x m/s and y m/s

Length of 1^{st} train = 27x meter

Length of 2^{nd} train = 17y meter

Now,

(27x + 17y)/(x+y) = 23

Or, 4x = 6y

Or, x/y = 3/2

- A tank has two leakages. The first leakage alone can empty the tank in 9 min and the second alone would have done it in 6 min. If water leaks out at a constant rate, how long does it take both the leakage together to empty the tank?

(A) 5 min

(B) 3.5 min

(C) 4 min

(D) 3.6 min

Answer: (D) 3.6 min

1^{st} leakage empties 1/9 in 1 min

2^{nd} leakage empties 1/6 in 1 min

They together empty (1/9 + 1/6) = 5/10 in 1 min

So, time taken = 18/5 = 3.6 min

- The time taken by a man to travel 36 miles downstream is 90 min less than to go the same distance upstream. The speed of the man in still water is 10 mph. Find the speed of the stream.

(A) 2 mph

(B) 2.5 mph

(C) 3.5 mph

(D) 5 mph

Answer: (A) 2 mph

Exp:

Let the speed of the stream x mph.

Then, Speed downstream = (10 + x) mph,

Speed upstream = (10 – x) mph.

Now,

36/(10-x) – 36/(10+x) = 90/60

Or, (x + 50)(x – 2) = 0

Or, x = 2

- A boat runs at 22 km per hour along the stream and 10 km per hour against the stream. Find the ratio of the speed of the boat in still water to that of the speed of the stream.

(A) 2:3

(B) 5:3

(C) 7:3

(D) 8:3

Answer: (D) 8:3

Exp:

Speed along the stream = a = 22 km/hr

And speed against the stream = b = 10 km/hr.

Now, the speed in still water = (a + b) / 2 km/hr = (22 + 10) / 2 = 16 km/hr.

And the speed of stream = (a – b) / 2 km/hr = (22 – 10) / 2 = 6 km/hr.

Required ratio = speed in still water : speed of stream = 16:6 = 8:3

- In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?

(A) 30%

(B) 70%

(C) 100%

(D) 250%

Answer: (B) 70%

Required percentage ={(295/420) x 100}%

=(1475/21)%

= 70% (approximately).
