Answer 2

Answer:

No.of days taken by 10 men to complete the full work = 60 days

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

No. of days taken by 10 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 = 10×48

= 480

No. of days taken by (10+70) = 80

Men to complete 4/5 of full work = (10×48)/80

= 480/80 days

= 6 days
