of a job in 10 days. At this rate, how many more days will it takes him to finish the job?
Answer: Option
Explanation:
| Work done = | 5 |
| 8 |
| Balance work = |  |
1 - | 5 |  |
= | 3 |
| 8 | 8 |
Let the required number of days be x.
| Then, | 5 | : | 3 | = :: 10 : x |  |
5 | x x = | 3 | x 10 |
| 8 | 8 | 8 | 8 |
 x = |
|
3 | x 10 x | 8 | |
| 8 | 5 |
x = 6.

From 8/8 of total work, 5/8 part done in 10 days.
For one part he took 2 days.
10/5 = 2.
Then balance 3/8 part he will take.
3x2 days = 6 days.

5/8 work completed in 10 days.
Total work will complete = 10*(8/5) = 80/5 = 16.
Therefore remaining work (1-5/8) done on = 16-10 days = 6 days.
Total work will complete = 10*(8/5) = 80/5 = 16.
Therefore remaining work (1-5/8) done on = 16-10 days = 6 days.

Take the problem in the following way:.
A man can complete 5/8 of a work in 10 days. How long does it take to complete 3/8 of the same work?

@Chandrasekar
Its too simple logic..
Consider the work done be 1.
They have completed 5/8 of work.
So remaining is 1-(5/8)=(8-5)/8=3/8

In 1 day (5/8)/10 = 0.0625 part work is done.
Hence,
No.of days taken to complete this = 1/0.0625 = 16.
Remaining days = 16-10 = 6.
Hence,
No.of days taken to complete this = 1/0.0625 = 16.
Remaining days = 16-10 = 6.

5/8 of the work could be completed in 10 days.
So, full work could be completed in 10*8/5 = 16 days.
Extra days = 16 -10 = 6 days.
So, full work could be completed in 10*8/5 = 16 days.
Extra days = 16 -10 = 6 days.

It's so simple:
Total of 8 parts 5 parts done in 10 days:
Remaining 3 parts in 6 days:
1 part = 2 days.
Total of 8 parts 5 parts done in 10 days:
Remaining 3 parts in 6 days:
1 part = 2 days.

Job Day(s).
5/8 10
1/8 10/5=2
8/8
(i.e.=1) 2X8=16
Remaining Days = 16-10 = 6.
5/8 10
1/8 10/5=2
8/8
(i.e.=1) 2X8=16
Remaining Days = 16-10 = 6.

5/8 job = 10 days,
1 job = 10 * 8/5,
1 job = 16 days,
16 - 10 days = 6 days.
1 job = 10 * 8/5,
1 job = 16 days,
16 - 10 days = 6 days.
