Explanation:
The Healing Brush and Patch tools add extra features. They match the texture, transparency, lighting, and shading of the sampled area. Instead of replacing them, pixel for pixel, like the clone stamp. This causes the painted pixels to blend seamlessly into the rest of the image. Using the Healing Brush tool: 1. Select the Healing Brush tool in the toolbox.

Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
