Answer: Option B

Explanation:

Let the radius of the smaller circle be r cm
Then, radius of bigger circle = (r + 14)cm
Given, π(r + 14) 2−π(r) 2 = 1056
⇒ π(r 2 + 28r + 196)−πr 2 = 1056
⇒πr 2 + 28πr + 196π−πr 2 = 1056
⇒28 × 22/ 7 + 196x22/ 7 = 1056
= >88r + 616 = 1056
⇒r = 5 cm.

2915 . The difference between two numbers is 5 and the difference between their square is 65. What is the smaller number?

A. 9
B. 5
C. 11
D. 13

View Answer	Favorite Question

Answer: Option A

Explanation:

ধরি, সংখ্যা দুটি x ও y যেখানে x > y

x - y = 5

x2 - y2 = 65

( x + y) ( x - y) = 65

( x + y) 5 = 65

x + y = 65/5

x + y = 13

বড় সংখ্যাটি = ( x + y) + ( x - y) / 2 = 13 + 5/2 = 9.

View Answer	Favorite Question

Answer: Option B

Explanation:

ধরি, বড় সংখ্যা= x, ছোট সংখ্যা=y

প্রশ্নমতে, x - y =7……….(1)

xy =60 => x => 60/y

(1) নং এ x এর মান বসিয়ে পাই,

60/y - y =7

=> 60 - y2 - 7y =0

=> y2 +7y - 60= 0

=> y2 +12y -5y -60=0

=> y(y+12)-5(y+12)=0

=> (y+12)(y-5)=0

So, y = 5 but y≠-12

A. 18
B. 24
C. 30
D. 40

View Answer	Favorite Question

Answer: Option B

Explanation:

Let the larger and smaller numbers be X and 3X/5 respectively.

Then, X - 3X/5 = 16

or, (5X - 3X)/5 = 16

or, 2X = 80

or, X = 40

So, the smaller number, 3X/5 = 3×40/5 = 24

View Answer	Favorite Question

Answer: Option D

Explanation:

Let the two consecutive odd integers be (2x+1) and (2x+3)

Then according to the question

⇒(2x+3)²−(2x+1)²=4x²+12x+9−4x²−4x−1

⇒8x+8

⇒8(x+1)

Hence the difference between the squares of two consecutive odd integers is always divisible by 8

B. 28 and 17
C. 28 and 18
D. 28 and 19

View Answer	Favorite Question

Answer: Option B

Explanation:

Let's call the two numbers x and y. We're given two pieces of information:

The difference between the two numbers is 11: x - y = 11.

One-fifth of their sum is 9: (1/5)(x + y) = 9.

We can start by solving the first equation for one of the variables and then substitute it into the second equation:

From the first equation, we can express y in terms of x: y = x - 11.

Now, substitute this expression for y into the second equation:

(1/5)(x + x - 11) = 9

Now, simplify and solve for x:

(1/5)(2x - 11) = 9

Multiply both sides by 5 to get rid of the fraction:

2x - 11 = 45

Add 11 to both sides:

2x = 45 + 11 2x = 56

Now, divide by 2:

x = 56 / 2 x = 28

Now that we have found x, we can find y using the first equation:

y = x - 11 y = 28 - 11 y = 17

So, the two numbers are 28 and 17.
