Answer: Option A

Explanation:

ধরি, সংখ্যা দুটি x ও y (x>y)

xy = 90 - - - - - (1)

এবং (x + y) - (x - y) = 30

2y = 30

y = 15

1 থেকে পাই x = 900/15 = 60

Answer: Option C

Explanation:

Hints : Let the numbers be 37a and 37b

Then, 37a × 37b = 4107

ab = 3

Now, Co primes with product 3 are (1, 3)

So, the required numbers are (37 × 1, 37 × 3) = ( 37, 111)

Areater number = 111

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.

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

Answer: Option D

Explanation:

Purchasing price of each apple = 1/15

Selling price of each apple = 1/12

Gain percentage = (1/12 - 1/15) / (1/15) × 100% = (5 - 4)/60 / (1/15) × 100% = 1/60 × 15 × 100% = 25%

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

Answer: Option A

Explanation:

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

3x = 2x + 2y

x = 2y

x/y = 1/2 = 1 : 2
