3. Compute the Euclidean Distance (D1), City-block Distance (D2) and Chessboard distance (D3) for
points p and g, where p and q be (1, 2, 3) and (1, 5, 7) respectively. Give answer in the form (D1,
D2, D3).
a) (5, 3, 4)
b) (5, 4, 3)

Answer :-
4. What is the minimum bandwidth required to transmit a grayscale image scanned at 100 PPI of size
3 inches x 4 inches, with a data compression ratio of 8:1, over a communication channel in 0.5
seconds, given that each pixel is digitized using 8 bits?
Hint: Data compression ratio is defined as the ratio between the uncompressed size and compressed
size: Thus, a representation that compresses a file’s storage size from 10 MB to 2 MB has a
compression ratio of 10/2 = 5/1
a) 3.84 Gbps
b) 1.92 Gbps
c) 1.48 Gbps
d) 5.12 Gbps
Answer :-
