3271 . The profit earned after selling an article for Tk.3,362 is the same as the loss incurred after selling the article for Tk.2,346. At what selling price will a trader make a 20% profit on this article?

A. 4639.4
B. 4769.6
C. 4830.8
D. None of these

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Let the cost price of the article be Tk. x.

∴ 3362 − x = x − 2346

∴ x = C.P. = 3362 + 2346 = 2,854/ -

∴ S.P. corresponding to a 20% profit = 1.2 × 2854 = Tk. 3,424.8/ -

Hence, option D is correct.

3272 . The profit earned by selling an article for Tk. 832 is equal to the loss incurred when the same article is sold for Tk. 448. What should be the sale price for making 50% profit? Created: 5 y

A. Tk. 920
B. Tk. 960
C. Tk. 1060
D. Tk.1200

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Hints: Let, cost price be TK x

Then, (832 - x) /x ×100 = (x - 448)/x ×100

832 - x = x - 448

2x = 1280

x = 640

Profit = 50% of TK 640 = Tk.( 50/100)×640 = TK 320

So, the required sales price is (640 + 320) Tk. = Tk. 960

3280 . The ratio between the length and breadth of a field is 7 : 5. The perimeter of the field is 360 meter. What is the area of the field?

A. 31000 sq. meter
B. 31500 sq. meter
C. 7875 sq. meter
D. 8775 sq. meter

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

Let the length and breadth be 7x and 5x meters respectively.

Then, perimeter, 2(7x + 5x) = 360

or, 2×12x = 360

or, 24x = 360

or, x = 360/24 = 15

Area = length×breadth = 7x × 5x = 35x2 = 35×152 = 35×225 = 7875 m2
