no.of days taken by 210 men to complete the full work =60 days

work completed in 12 days = 1/5 of full work

no. of days taken by 210 men to complete (4/5 of full work)# =60-12=48 days

no. of days taken by 1 man to complete 4/5 of full work=210*48

no. of days taken by (210+70)=280 men to complete 4/5 of full work=210*48/280=36 days

#4/5 of the full work refers to the remaining work to be completed.
