Answer: Option C

Explanation:

There are 8 even integers before 42 and the other 8 integers are after 42.

The third of them will be 42 - 2 - 2 - 2 - 2 - 2 - 2 = 42 - 12 = 30.

[Alternatively, The first one will be 42 - (8 x 2) = 42 - 16 = 26.

The third one will be 26 + 2 + 2 = 30]

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

E. TK. 500

Answer: Option B

Explanation:

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

E. Tk.18.00

View Answer	Favorite Question

Answer: Option A

Explanation:

২০% লাভে রিটেইলারের বিক্রয়মূল্য = ১০০+২০ =১২০ টাকা

ক্রয়মূল্য ১২০ টাকা হলে বিক্রয়মূল্য ১০০ টাকা

ক্রয়মূল্য ১ টাকা হলে বিক্রয়মূল্য ১০০ /১২০ টাকা

ক্রয়মূল্য ২১.৬০ টাকা হলে বিক্রয়মূল্য ১০০ *২১.৬/১২০ টাকা

= ১৮ টাকা

( যা উৎপাদকের বিক্রয়মূল্য)

২০% লাভে প্রডিউছারের বিক্রয়মূল্য ১২০ টাকা

বিক্রয়মূল্য ১২০ টাকা হলে উৎপাদন খরচ ১০০ টাকা

বিক্রয়মূল্য ১ টাকা হলে উৎপাদন খরচ ১০০ /১২০ টাকা

বিক্রয়মূল্য ১৮ টাকা হলে উৎপাদন খরচ ১০০*১৮/১২০ টাকা

= ১৫ টাকা

Answer: Option D

Explanation:

To form a task force consisting of one member of X and one member of Y, you can use the concept of combinations. Since committee X has 4 members and committee Y has 5 members, you have choices for selecting one member from each committee.

The number of different task forces possible is the product of the number of ways you can choose one member from each committee.

Number of ways to choose one member from X = C(4, 1) = 4 (choose 1 from 4) Number of ways to choose one member from Y = C(5, 1) = 5 (choose 1 from 5)

Total number of different task forces = 4 (from X) * 5 (from Y) = 20

So, there are 20 different task forces possible.
