Answer:
The work will be finished in 10 days.
Step-by-step explanation:
Rashid can do a piece of work in 8 days
This means that each day he works, Rashid does
of the work.
Tipu can finish in 12 days.
This means that each day he works, Tipu does
of the work.
Each 2 days:
Each 2 days they work, the amount done is given by:

Each 2 days, 5/24 of the work is done:
The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:

2*4.8 = 9.6
Rounding up
The work will be finished in 10 days.

Answer:
The probability that a randomly chosen code starts with M and ends with E is 0.05 ....
Step-by-step explanation:
According to the given statement we have to make five letter code from A, F, E, R, and M without repeating any letter. We have to find that what is probability that a randomly chosen code starts with M and ends with E.
Thus the probability of picking the first letter M = 1/5
After that we require the sequence (not E, not E, not E) which is equal to:
= 3/4 * 2/3* *1/2
= 1/4
Now multiply 1/5 and 1/4
1/5 * 1/4
= 1/20
= 0.05
Therefore the probability that a randomly chosen code starts with M and ends with E is 0.05 ....
