Question

Computer A takes 3 minutes to process an input while /computer B takes 5 minutes. If computers A, B and C can process an average of 14 inputs in one hour, how many minutes does computer C alone take to process one input ?
​

Answer 1

Answer:

6minutes

Step-by-step explanation:

Number of units processed by computer A in 1 minute

=1/3

Number of units processed by computer B in 1 minute

=1/5

Number of units processed by computer A, B and C in 1 minute

=14×3÷60 = 7/10

Number of units processed by computer C in 1 minute

=7/10−(1/3+1/5)

=7/10−8/15

=5/30

=1/6

Hence, computer C takes 6 minutes to process one input alone.
