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.

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

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.

It can be solved this way also
To complete 5/8 part --- 10 days
To complete 8/8 parts ---- ? days
Solving, {(8/8) x 10}/{5/8} = 16 days
Therefore remaining days = 160- 10 = 6 days
To complete 5/8 part --- 10 days
To complete 8/8 parts ---- ? days
Solving, {(8/8) x 10}/{5/8} = 16 days
Therefore remaining days = 160- 10 = 6 days

Hey guys its very easy...
5/8 work can be done in 10 days
So 1 work can be done in 10/(5/8) days=10*8/5=16 days
Hence remaining(1-5/8=3/8)work can be done in 16*3/8
=6 days
5/8 work can be done in 10 days
So 1 work can be done in 10/(5/8) days=10*8/5=16 days
Hence remaining(1-5/8=3/8)work can be done in 16*3/8
=6 days

Very easy
For 5 parts work he takes 10days
for 3 parts ?
3*10/5=6days
For 5 parts work he takes 10days
for 3 parts ?
3*10/5=6days

@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
