C. 58
D. 60

View Answer	Favorite Question

Answer: Option C

Explanation:

To find the next number in the sequence, we can look for a pattern in the differences between consecutive terms:

4 - 3 = 1 8 - 4 = 4 17 - 8 = 9 33 - 17 = 16

We can see that the differences between consecutive terms are perfect squares: 1^2, 2^2, 3^2, and 4^2. This suggests that the pattern might be related to square numbers.

Let's continue this pattern:

The next perfect square after 4^2 (16) is 5^2 (25).

So, to find the next term in the sequence, we add the next square number:

33 + 25 = 58

Therefore, the next number in the sequence is 58.

6 - 11 = 5

11 - 18 = 7

18 - 27 = 9

27 - 38 = 11

সুতরাং পরবর্তী সংখ্যাটি 38.

Explanation:

পরের সংখ্যা হতে আগেরটি বিয়োগ করলে পাই,

৬-৩= ৩; ১১-৬=৫; ১৮-১১=৭; ২৭-১৮=৯

অর্থাৎ, প্রথম সংখ্যার সাথে ধারাবাহিক ভাবে odd number যোগ করলে পরের সংখ্যা পাওয়া যায়।

৯ এর পরে odd 11.

পরবর্তী সংখ্যা (২৭+১১)=৩৮

Answer: Option C

Explanation:

প্রশ্নানুসারে,

3 × b + 2 = a

∴ a = 3b + 2

আবার, 3 × 2 + 1 = b

∴ b = 7

∴ a = 3 × 7 + 2

= 23.

3010 . The number of flights leaving a certain airport doubles during every one-hour period between its 9 am opening and noon; afternoon, the number of flights leaving from the airport doubles during every two-hour period. If 4 flights left from the airport between 9 am and 10 am, how many flights left the airport between 2 pm and 4 pm?

D. 64
E. None of these

Answer: Option D

Explanation:

9 টা থেকে noon অর্থাৎ 12টা পর্যন্ত flight সংখ্যা double হয় প্রতি 1 ঘণ্টায় । 9 টা থেকে 10 টায় ছুটি flight হলে 10 - 11 টায় 2x, 11  -  12 টায় 4x / Noori - এর পর প্রতি দুই ঘণ্টায় হয় দ্বিগুণ। 12  - 2 টায় ৪r 2টা থেকে 4টায় হয় 16x, তাহলে x  =  4 দেওয়া আছে। সুতরাং ফ্লাইট সংখ্যা  =  16x  =  16   ×  4  =  64

Answer: Option D

Explanation:

To find the number of parallelograms that can be formed from a set of four parallel lines intersecting another set of three parallel lines, you can use the following method:

Understand the pattern: Each parallelogram can be formed by selecting two vertical lines and two horizontal lines that intersect to create a closed shape.

Count the vertical lines: There are 4 vertical lines in the first set.

Count the horizontal lines: There are 3 horizontal lines in the second set.

Choose two vertical lines: You can choose 2 out of the 4 vertical lines in C(4, 2) ways, where C(n, k) represents the combination of n items taken k at a time.

Choose two horizontal lines: Similarly, you can choose 2 out of the 3 horizontal lines in C(3, 2) ways.

Calculate the total number of parallelograms: To find the total number of parallelograms, multiply the number of ways to choose vertical lines by the number of ways to choose horizontal lines:

Total parallelograms = C(4, 2) * C(3, 2)

Now, calculate:

C(4, 2) = 4! / (2!(4-2)!) = 6

C(3, 2) = 3! / (2!(3-2)!) = 3

Total parallelograms = 6 * 3 = 18

So, the number of parallelograms that can be formed is 18. The answer is indeed 18.
