B. 140
C. 6
D. 3
E. None of these

View Answer	Favorite Question

Answer: Option E

Explanation:

Velocity = Distance / time = 240 m / 8 sec = 30 m/s

Now, 1 m/s = 1/1000 km/s = (1/1000) x 60 x 60 km/h = 3.6 km/h

So, 30 m/s = 30 x 3.6 km/h = 108 km/h

B. Tk.6666.67
C. Tk.5555.56
D. Tk.4444.44
E. None of these

Answer: Option A

Explanation:

Their sales exceeded the basic quota of TK 200000 by 400000, 250000 and 100000 respectively.

So, Mr. Saif will receive a bonus amount = {100000/(400000 + 250000 + 100000)}x25000 = 3333.33 TK.

Explanation:

7 . A car goes 15 miles on a gallon of octen when it is driven at 50 miles per hour. When the car is driven at 60 miles per hour, it only goes 80% as far. How many gallons of octane is needed to travel 200 mile if half the distance is traveled at 50 miles per hour and the rest at 60 miles per hour?

A. 13.33
B. 16.67
C. 10.6
D. 15
E. None of these

View Answer	Favorite Question

Answer: Option D

Explanation:

A car goes 15 km with a gallon of octane at 50 km/hr.

Again,

If travels with 60 km/hr, it goes 80% far as that of before. i.e.

D = 80%×15 = 12 km.

Now,

According to question, if 100 km is travelled in 50 km/hr and another 100 km in 60 km/hr then,

In 50 km/hr: 1 gallon = 15 km

In 60 km/hr: 1 gallon = 12 km

Hence,

Total required gallons of octane is;

100/15 + 100/12

= 15 gallons.

8 . A certain bakery ran a promoion: a customer can but x donuts for the regular price of Tk.15 total and get 3 donuts free. If the donut price per dozen during the promotion is Tk 2 less than the normal donut price per dozen, what is the value of x?

A. 15
B. 18
C. 21
D. 25

View Answer	Favorite Question

Answer: Option A

Explanation:

Let's break down the information provided:

During the promotion, a customer can buy x donuts for the regular price of Tk. 15 and get 3 donuts free.
The donut price per dozen during the promotion is Tk 2 less than the normal donut price per dozen.
Let's denote the normal price per dozen as "P" (in Tk).

So, during the promotion:

Price for x donuts (including 3 free donuts) = Tk. 15
Price per dozen during the promotion = P - 2 Tk
Now, let's set up the equation for the price of x donuts during the promotion:

(x + 3) * (P - 2) = 15

Now, we need to find the value of x. We know that P is the price per dozen during the normal period.

To solve for x, we'll first express P in terms of x:

P = (15 / (x + 3)) + 2

Now, we need to find a value of x for which P is a multiple of 5 (to make the total price of x donuts equal to Tk. 15). We'll try different values of x:

If x = 15: P = (15 / (15 + 3)) + 2 = 1 + 2 = 3 The total price for 15 donuts (including 3 free) at Tk. 3 per dozen would be Tk. 15.
So, the value of x is indeed 15, and this satisfies the condition of the promotion.

Therefore, x = 15.

Answer: Option E

Explanation:

Remaining books = 1 - 2/3 = 1/3

1/3 of the books = 36

So, 2/3 of the books = 36 x (2/3) / (1/3) = 72

Then, total amount received from the sold books = 72 x 2.3 = 165.6 TK.

11 . A motor pool has 300 vehicles of which 30% are trucks. 20% of all the vehicles in the motor pool are diesel, including 15 trucks. What percent of the motor pool is composed of vehicles that are nither trucks nor diesel?

A. 165%
B. 90%
C. 65%
D. 10%
E. None of these

View Answer	Favorite Question

Answer: Option E

Explanation:

Trucks = 30% of 300 = 90

Other Vehicles (Excluding Trucks) = 300 - 90 = 210

Diesel Vehicle = 20% of 300 = 60 (Including 15 Trucks)

Other Diesel Vehicles (Excluding Trucks) = 60 - 15 = 45

Trucks that are NOT diesel = 90 - 15 = 75

Other Vehicles that are NOT diesel Vehicles = 210 - 45 = 165

Required % = (165/300)×100 = 55%

12 . A motorcyclist rode to work at an average speed of 15 miles per hour and returned home along the same route at an average speed of 45 miles per hour. If his entire traveling time was 1 hour, what was the total number of miles in the round trip?

A. 30
B. 36.5
C. 45
D. 15
E. 22.5

View Answer	Favorite Question

Answer: Option E

Explanation:

He travels 20 miles at a speed of 15 mph so he takes 20/15 = 4/3 hrs to travel one way. Since total time is 2 hrs, he must have taken 2 - 4/3 = 2/3 hrs while returning.
Speed while returning = 20/(2/3) = 30 mph

View Answer	Favorite Question

Answer: Option E

Explanation:

We know, divident = quotient x divisor + remainder

So, divident = quotient x 105 + 99

Now, 105 is completely divisible by 21 yielding the quotient 5. So, we only need to divide the remainder 99 by 21 to see if any remainder remains.

Now, 99 = 4 x 21 + 15. So, 15 will be remained as a remainder if the number is divided by 21 instead of 105.

15 . A passenger paid 50% customs duty on accompanied baggage items. He paid another 20% sales tax on the total value of the items plus the custom duty paid. The total custom duty and sales tax is Tk. 350. what is the value of the item custom duty and sales tax?
