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.

View Answer	Favorite Question

Answer: Option D

Explanation:

Let the usual revenues be L and E respectively. So, total usual revenue is (L + E).

New revenue from luxury car sales = L - 11% of L = L - 0.11L = 0.89L

New revenue from economy car sales = E - 7% of E = E - 0.07E = 1.07E

New total revenue = 0.89L + 1.07E

ATQ, {(0.89L + 1.07E) - (L + E)} / (L + E) = 1/100

or, 100(0.89L + 1.07E - L - E) = L + E

or, 100(0.07E - 0.11L) = L + E

or, 7E - 11L = L + E

or. 11L + L = 7E - E

or, 12L = 6E

or, L/E = 6/12 = 1/2

or, L : E = 1 : 2

Explanation:

205 . Equal amounts of water were poured into two empty jars of different capacities, which made one jar 1/4 full and another jar 1/3 full.. If the water in the jar with the lesser capacity is then poured into the jar with the greatest capacity, what fraction of the larger jar will be filled with water?

A. 1/3
B. 1/4
C. 1/2
D. 1/5
E. None of these

View Answer	Favorite Question

Answer: Option E

Explanation:

Evidently, 1/3 full jar is of the lesser capacity as 1/3 is greater than 1/4. As equal amount of water was poured into each jar, pouring water from the jar of lesser capacity to the larger jar will make the amount of water in the larger jar to get doubled.

Therefore, the fraction of larger jar filled with water will be = 2 x 1/4 = 1/2

206 . Everyone has their morning beverages differently . Rumana and Deepti both take sugar in their drinks. Rumana, Osman and Mahboob all drink tea while the other three drink coffee. Masud and Mahboob have milk in their beverages . Those who don't add anything , take their beverages black. What does Waquar drink ?

A. Tea with sugar
B. Coffee with milk
C. Black tea
D. Coffee with sugar
E. Black coffee

View Answer	Favorite Question

Answer: Option E

Explanation:

From the given information, we can create a table to organize the data:

Name Beverage Sugar Milk

Rumana Tea Yes No

Deepti Coffee Yes No

Osman Tea No No

Mahboob Tea No Yes

Masud Coffee No Yes

(Unknown) Coffee/Tea ? No

We need to determine what Waquar drinks, and whether they add sugar and/or milk to their beverage. We can see that there are only two people left who have not been assigned a type of beverage: Waquar and the unknown person. Since Rumana, Osman, and Mahboob all drink tea, we can assume that the unknown person drinks coffee. This means that Waquar also drinks coffee, since all six people drink either tea or coffee.

Now we need to determine whether Waquar takes sugar and/or milk in their coffee. From the information given, we know that Deepti takes sugar in her coffee, and Mahboob and Masud have milk in their beverages. There is no information given about whether Waquar takes sugar or milk in their coffee, so we cannot determine this with certainty. Therefore, the answer is that we do not know whether Waquar takes sugar and/or milk in their coffee. We only know that they drink coffee

=10+5+(10×5)/100

=15.5%

Again,

a'+b'+(ab)'/100

=3.95%

So, 10000+(10000×3.95%)=10395
