Solution
Work does one =`5/21`
Remaining work =`1-5/21=16/21`
`5/21` of a work can be done in 6 days working 10 hours a day by = 10 m
1 work can be done in 6 days working 10 hours a day by =`(10xx21)/5`
1 work can be done in 1 day working 10 hours a day by =`(10xx21xx6)/5` men
`16/21` work can be done in 8 days working 10 hours a day by =`(10xx21xx6xx16)/(5xx21xx8)` = 24 men
