Let's assume the capacity of each bucket is 'x'. 

- Therefore, the capacity of 25 buckets will be 25x. 

- Now, the capacity of the bucket is reduced to two-fifth of its present, so the new capacity of the bucket will be (2/5)x. 

To find the new number of buckets required to fill the tank, 

we can use the formula: New number of buckets = Tank capacity / Capacity of each bucket 

- The tank capacity remains the same, so it is still 25x. 

- The capacity of each bucket is now (2/5)x. Therefore, the new number of buckets required will be: 

New number of buckets = 25x / (2/5)x = (25x * 5/2x) = 62.5 

Therefore, 62.5 buckets of water will be required to fill the same tank with the reduced capacity bucket. Hence, the correct answer is option (c) 62.5.

Let the number of wickets taken by bowler after the match be N.

So, number of runs given by bowler after match =(N−5)×12.4 +26 

                                                                                     =12.4N−62+26

                                                                                     =12.4N−36

Average of bowler after match =$\frac{\mathrm{N}12.4\mathrm{N}-36}{\mathrm{N}}$

As per question , average of bowler after match =12.4−0.4=12

Equating both averages , we get 

$\frac{\mathrm{N} 12.4\mathrm{N}-36}{\mathrm{N}}$ = 12 
 

12.4N−12N = 36

N = $\frac{36}{0.4}$​

N=90

So, Number of wickets taken by bowler till last match =N−5=90−5=85

Let their present ages be 4x, 7 x and 9x years respectively.

Then, (4x - 8) + (7 x - 8) + (9x + 8) =56⇔20x = 80

x = 4

∴ Their present ages are 16 years, 28 years and 36 years respectively

No. of  sweets each student get = 20% of 65 = 13

No. of sweets each teacher get = 40% of 65 = 26

No. of sweets distributed to 65 students =  13 × 65 = 845

No. of sweets distributed to 4 teachers = 4 × 26 = 104

Therefore, the total no. of sweets there = 845 + 104 = 949.

• Fragmentation refers to the condition of a disk in which files are divided into pieces scattered around the disk. 
• Fragmentation occurs naturally when you use a disk frequently, creating, deleting, and modifying files.
•  At some point, the operating system needs to store parts of a file in noncontiguous clusters.
• This is entirely invisible to users, but it can slow down the speed at which data is accessed because the disk drive must search through different parts of the disk to put together a single file.
• Fragmentation causes a huge degradation in system performance, and over time can bring your system to a near crawl. 
• Fragmentation causes your computer to use excessive resources (memory and CPU time) to complete tasks related to reading and writing files. 
• Fragmentation can cause applications to launch more slowly, file access to take longer, system boot or shutdown to slow, slow system hibernation or resume from hibernation, causes videos to drop frames and music to skip.
• Optical storage devices use low beam laser to write retrieve data, so there is fragmentation in an optical disk it will be hard for laser to read and write data. 

ছয়টি প্রধান সমাস ছাড়াও কয়েকটি অপ্রধান সমাস রয়েছে। যেমন: প্রাদি, নিত্য, অলুক, উপপদ ইত্যাদি। এসব সমাসের প্রচুর উদাহরণ পাওয়া যায় না। এজন্য এগুলোকে অপ্রধান মনে করা হয়।

The quality of the print largely depends on the resolution, which is the number of dots per inch (DPI) or pixels per inch (PPI). The higher the resolution, the sharper and more defined the image will be. Nowadays, most printers have a resolution of at least 300 DPI or 300 PPI.

Web cam is an input unit device.

A webcam is a hardware camera and input device that connects to a computer and the Internet and captures either still pictures or motion video of a user or other object. Today, most webcams are either embedded into the display with laptop computers or connected to the USB or FireWire port on the computer.

A webcam is an input device because it captures a video image of the scene in front of it. It is either built in to the computer (e.g. laptop) or it is connected through an USB cable.

The term webcam is a combination of "Web" and "video camera." The purpose of a webcam is, not surprisingly, to broadcast video on the Web. Webcams are typically small cameras that either attach to a user's monitor or sit on a desk. Most webcams connect to the computer via USB, though some use a Firewire connection.

#NAME? is a common Excel error notation that appears when a formula or function cannot find the referenced data it needs to complete the calculation. This could be caused by a few different things, such as a misspelling in the formula name or an invalid reference.
