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.

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

View Answer	Favorite Question

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

3069 . The profit earned by selling an article of Tk. 900 is double the loss incurred when the same article is sold for Tk. 450. At what price should the article be sold make 25% profit?

C. Tk. 750
D. None of these

900 - x = 2 ( x - 450)

x = 600 tk

Cost price = 600 gain required is 25%

Sells price = [ (100 + 25) ×600] /100

= Tk. 750

3074 . 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

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

3075 . The ratio between the length and the perimeter of a rectangular plot is 1:3. What is the ratio between the length and breadth of the plot?

A. 1:2
B. 3:2

D. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Hints: Let the length is x and breadth is y. Then perimeter = 2 ( x + y)

Now, x / 2(x + y) = 1/3

3x = 2x + 2y

x = 2y

x/y = 1/2 = 1 : 2
