A. 25%

C. 30%
D. 33.33%

View Answer	Favorite Question

Answer: Option A

Explanation:

5 টি আপেলের ক্রয়মূল্য = 10 টাকা

∴ 1 টি আপেলের ক্রয়মূল্য = 10/5 টাকা = 2 টাকা

আবার, ৪টি আপেলের বিক্রয়মূল্য = 10 টাকা

∴ 1 টি আপেলের বিক্রয়মূল্য = 10/4 = 2.5 টাকা

শতকরা লাভ = {(2.5 - 2/2) × 100 }% = 25 %

182 . At 10 a.m two trains started traveling toward each other from station 287 miles apar. They passed each other at 1 : 30 pm the same day. They average speed of the slower train by 6 miles per hour. Which of the following represents the speed of the faster train in miles per hour?

A. 38
B. 40
C. 44
D. 48
E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

Let the average speed of slower and faster trains be S and (S + 6) miles/hr respectively.

Time taken = 10 am to 1:30 pm = 3.5 hr

Distance travelled by slower train = 3.5S

Distance travelled by faster train = 3.5(S + 6)

Now, 3.5S + 3.5(S + 6) = 287

or, 3.5S + 3.5S + 21 = 287

or, 7S = 287 - 21

or, 7S = 266

or, S = 266/7 = 38 miles/hr

So, speed of the faster train, S + 6 = 38 + 6 = 44 miles/hr

A. 40 & 42
B. 39 & 41
C. 38 & 40
D. 37 & 39
E. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

Total amount paid if bonus was 10% = 35.50 + 10% of 35.50 = 35.50 + 3.55 = 39.05 TK

Total amount paid if bonus was 15% = 35.50 + 15% of 35.50 = 35.50 + 5.325 = 40.825 TK

So, the total amount paid must have been in between 39 TK & 41 TK.

A. Tk.1.80
B. Tk.2.61
C. Tk.2.70
D. Tk.3.51
E. Tk.3.60

View Answer	Favorite Question

Answer: Option E

Explanation:

The call lasted for 1 minute and 27 seconds, which is a total of 87 seconds. Any call duration of less than 30 seconds is rounded up to the nearest 30-second unit, so the duration of this call will be rounded up to 90 seconds, which is 3 units of 30 seconds.

The first 30-second unit costs Tk. 1.80, so the cost of the first unit is Tk. 1.80.

The remaining 2 units of 30 seconds each cost Tk. 0.90 per unit, so the cost of the remaining units is Tk. 0.90 x 2 = Tk. 1.80.

Therefore, the total cost of the call is Tk. 1.80 + Tk. 1.80 = Tk. 3.60.

Answer: Option B

Explanation:

৩২ টা পেয়ারা র মূল্য ৩০ টাকা হলে ১টা পেয়ারার মূল্য .৯৪ টাকা।

২৫% লস মানে, ৭৫ টাকা বিক্রয়মূল্য হলে ক্রয়মুল্য ১০০

০.৯৪ টাকায় ক্রয়মূলয় ১.২৫ টাকা

আবার, ২০% লাভ মানে, ক্রয়মূল্য ১০০ টাকা হলে বিক্রয়মূল্য ১২০

ক্রয়মুল্য ১.২৫ টাকা হলে বিক্র্যমূল্য (১২০*১.২৫)/১০০ = ১.৫ টাকা

তাই ১৮ টাকায় পেয়ারা বিক্রি করবে (১৮/১.৫) = ১২ টা পেয়ারা

Let cost price Tk. x

x + x/100 × x = 56

100 x + x2 = 5600

x^2 + 100x - 5600 = 0

x^2 + 140 x - 40 x - 5600 = 0

x ( x + 140) - 40 ( x + 140) = 0

( x + 140) ( x - 40) = 0

x = - 140 ( not acceptable)

x = 40
