2116 . If the sum of three consecutive integers is less than 75, what is the greatest possible value of the smallest one?

A. 22
B. 23
C. 24
D. 35
E. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

ধরি, সংখ্যা তিনটি যথাক্রমে

x - 1, x, x + 1

x - 1 + x + x + 1 <75

3x <75

x<75/3

x<25

যেহেতু x<25 এবং পূর্ণসংখ্যা সেহেতু x = 24

ছোট সংখ্যাটি = ( 24 - 1 ) = 23

2119 . If the sum of two numbers is 33 and their difference is 15, the smaller number is :

A. 9
B. 12
C. 15
D. 18

View Answer	Favorite Question

Answer: Option A

Explanation:

Let, the numbers are x and y

According to question,

x + y = 33.......(1)

x - y = 15.......... (2)

(1) + (2) = 2x = x = 24.

again , x + y = 33 (1)

x - y = 15...... (2)

(1) - (2) = 2y = 18

y = 9

So, smallest number is 9

A. 500
B. 400
C. 300
D. 200
E. 100

Answer: Option D

Explanation:

If the total cost C = 1000 + 0.2s, where 's' is the sales volume, the variable cost on sales of TK. 1000 will be Taka

Given that,

sales of volume (s) = 1000

We know that,

Total cost (C) = total fixed cost + total variable cost

then, C = 1000 + 0.2s

Total variable cost = 0.2s

= 0.2 × 1000

= 200 Tk.

2122 . If the total surface are of a hemisphere be 36. sq. cm, then its radius is

A. 3√2 cm
B. 3√3 cm
C. √3 cm
D. 2√3 cm

View Answer	Favorite Question

Answer: Option A

Explanation:

The total surface area of a hemisphere is given by the formula:

Surface Area = 2πr^2

where "r" is the radius of the hemisphere.

Given that the total surface area is 36 sq. cm, we can set up the equation:

2πr^2 = 36

Now, solve for "r":

r^2 = 36 / (2π)

r^2 = 18 / π

r = √(18 / π)

To simplify further, we can rationalize the denominator by multiplying both the numerator and denominator by π:

r = √(18π / (π * π))

r = √(18π / π^2)

r = (3√2π) / π

So, the radius of the hemisphere is (3√2π) / π cm.

Now, to express it in a simplified form, we can cancel out π:

r = 3√2 cm

So, the radius of the hemisphere is 3√2 cm.

2124 . If the two digit integers M and N are positive and have the same digits, but in reverse order, which of the following CANNOT be the sum of M and N?

A. 181
B. 165
C. 121
D. 99
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Let the first digit be xy, then the second digit would be yx.

xy = 10x + y
yx = 10y + x

sum = 11 (x+y)

so the sum has to be multiple of 11. 181 is not. so 181 be the answer
