Question 1 Explanation: 
Frame duration= 1/50,000
= 20 sec
Frame size= No.of bits per frame
= 8 bits
Bit Rate= Frame Rate * No.of bits per frame
= 50000*8
= 400 kbps
Question 2
What is the bitrate for transmitting uncompressed 800x600 pixel color frame with 8 bits/pixel at 40 frames/Second?
A
1536 Mbps
B
2.4 Mbps
C
15.36 Mbps
D
153.6 Mbps

Question 2 Explanation: 
Step-1: Given data, Uncompressed pixel = 800*600
Step-2: Each of 8 bit = 800*600 *8
Step-3: Bit rate for transmitting = 800*600 *8 *40 =153600000 bits
Step-4: Here, they are given in Mbps. 153600000 bits =153.6Mbps
