A. Tk. 24200
B. Tk. 24200
C. Tk. 48000
D. Tk. 48400

View Answer	Favorite Question

Answer: Option D

Explanation:

Assume that investment of C = x
Then, investment of A = 2x Investment of B = 2A/3 = 4x/3 (since ratio of investment of A : B = 2 : 3 i.e B = 2A/3) A : B : C
= 2x : 4x/3: x
= 2 : 4/3 : 1
= 6 : 4 : 3
B's Share = 157300 × 4/(6 + 4 + 3) = 157300 × 4/13 = 12100 × 4 = Tk. 48400.

Explanation:

Total tax of assessed = ( 240×4) Tk. = 960Tk.

Tk. 4 is tax of Tk. 100

Tk.960 is tax of Tk. ( 100/4 ×960) = 24000 Tk.

So, 60% of x = 24000Tk.

60x×x /100 = 24000

x = 2400000/60 = 40000 Tk.

growth in 1 second = ( 1/7 - 1/13) = 6 / 91

6/91 জন জন্মগ্রহন করে 1 sec

1 জন জন্মগ্রহন করে 91 / 6 second = 15. 17 second এ।

E. 3 to 4

View Answer	Favorite Question

Answer: Option E

Explanation:

Let the number of people over 21 years be x. 
Given that the number of people aged 21 or under  =  3x 
So total population  =  4x 
Required ratio  =  3x : 4x  =  3:4 
So the answer choice is (e) 3 to 4.

2259 . In a certain store, the profit is 320% of the cost. If the cost increases 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?

A. 30%
B. 70%
C. 100%
D. 250%
E. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

Cost = 100
Profit = 320% of 100 = 320
Selling price = 100 + 320 = 420
New cost = 100 + (25% of 100 )
= 100 + 25 = 125
New Profit = 420 - 125
= 295
New Profit Percenage = (295/420×100)%
=70.23%
=70%

Explanation:

ধরি, বালকের সংখ্যা x

বালিকার সংখ্য 3x/4

বালক - বালিকার মোট সংখ্যা ( x + 3x/4) জন = 7x/4 জন

বালকদের মধ্যে ফ্রেঞ্চ ভাষায় কথা বলে x এর 50/100 জন = x/2 জন

বালিকাদের মধ্যে ফ্রেঞ্চ ভাষায় কথা বলে 3x/4×2/3 = x/2 জন

মোট ফ্রেঞ্চ ভাষায় কথা বলে ( x/2 + x/2) জন = x জন

Answer: Option D

Explanation:

Correct option is A)

Let the number of boys be x.
Then, number of girls = 120% of x 100120×x=56x
