Solution:

40*40=1600 men-days of work done in 40 days

So, 10*(40+35+30+25+20)=1500 men-days in 50 days

remaining 100 men-days of work to be done by 15 men

in 6.667 days 15 men complete 100 men-days of work

So Total no. of days = 56.667 under the given condition

for the last 30 days, 40 men can complete the job in 30 days, so with 35 men 40*30 = 35*x x = 34.28 total days = 44.28

Amount of work = 40 person x 40 days = 1600 person days

In the scheme where 5 person leaves every 10th days:

 Period Pers Days PD Tot PD 00-10 40 10 400 400 11-20 35 10 350 750 21-30 30 10 300 1050 31-40 25 10 250 1300 41-50 20 10 200 1500 50-57 15 7 105 1605

So 57 days will be required.

one man rate = 1/1600 now work done by 40 men in 10days = 10/40 = 1/4 therefore now 35 guys would do the 3/4 work now rate at which 35 guys work is 35/1600 ..........this is work/day => 3/4 work would be donein 3/4*35/1600 which cmes out to be around 61

40 men work in 40 days
1 men work in 1600 days
suppose we have to work done 1600 units
and 1 men work in 1 day 1 unit
so 10 day work completed  10*40 equals 400 (40 men present)

20 day...........................10*35 equals 350
20 day...........................10*30 equals 300
40 day...........................10*25 equals 250
50 day...........................10*20 equals 200

In 50 day total work completed 1500 units (Now 15 men present)
56 day........................... 6*15 equals 90 units so
Remainning 10 units work copleted 10/15 equals 0.67
Total work completed in 56.67 day.

Men    Days     Units

40    *   40    =  1600
totally 1600 units of work to be done
10   *  40    = 400
10   *  35    = 350
10   *  30    = 300
10   *  25    = 250
since 1300 units of work has been completed
so remaining 300 units
10   *  20    = 200
remaining 100 units
logically
6.6  * 15     = 99

Totally we have 1599 units
