1081 . A room 5m x 8m is to be carpeted leaving a margin of 10 cm from each wall. If the cost of the carpet is Tk. 18 per sq. meter, the cost of carpeting the room will be:

A. Tk. 673.92
B. Tk. 682.46
C. Tk. 691.80
D. Tk. 702.60

View Answer	Favorite Question

Answer: Option A

Explanation:

The room dimensions are 5m x 8m. However, you need to leave a margin of 10 cm from each wall, which is equivalent to 0.1m. So, the effective dimensions for carpeting are (5m - 2 * 0.1m) x (8m - 2 * 0.1m).

Effective length = 5m - 2 * 0.1m = 4.8m Effective width = 8m - 2 * 0.1m = 7.8m

Now, calculate the area of the room to be carpeted:

Area = Effective length * Effective width Area = 4.8m * 7.8m = 37.44 sq. meters

Now, you know that the cost of the carpet is Tk. 18 per square meter. You can calculate the total cost:

Total Cost = Area * Cost per sq. meter Total Cost = 37.44 sq. meters * Tk. 18/sq. meter

Total Cost = Tk. 673.92

So, the cost of carpeting the room will be Tk. 673.92.

1083 . A room contains 200 people, 25% of whom are graduates. A group of people 30% of whom are graduates leave the room. Of the remaining people 10% are graduates. How many people did leave the room?

A. 150
B. 145
C. 125
D. 120

View Answer	Favorite Question

Answer: Option A

Explanation:

Let the number of people leaving be L.

Remaining people = 200 - L

Total graduates = 25% of 200 = 50

Leaving graduates = 30% of L = 0.3L

Remaining graduates = 50 - 0.3L

ATQ, 10% of (200 - L) = 50 - 0.3L

or, 20 - 0.1L = 50 - 0.3L

or, 0.3L - 0.1L = 50 - 20

or, 0.2L = 30

or, L = 30 / 0.2 = 150

∴ বড় টুকরার দৈর্ঘ্য (20.6 - 8.9) মিটার
= 11.7 মিটার

The salesman's commission for the month is 5/4 * 8000 = 10000.

Therefore, his total income for the month is 8000 + 10000 = 18000.

The fraction of his income that came from commission is:

10000 / 18000 = 5/9.

So, 5/9 of his income for the month came from commission.
