Work done by 8 men and 12 boys in 10 days= 1 workWork done by 8 men and 12 boys in 1 day= 1/10 workWork done by 6 men and 8 boys in 14 days= 1 workWork done by 6 men and 8 boys in 1 day= 1/14 workNow,(8 men and 12 boys)=1/10 ....Equation (1)(6 men and 8 boys)=1/14 .... Equation (2)Solving Equation (1) and (2), we getMan=1/140 and Boy=1/280So, 1 man can alone to finish the work=140 days1 Boy can alone to finish the work=280 days
Work done by 8 men and 12 boys in 10 days= 1 work
ReplyDeleteWork done by 8 men and 12 boys in 1 day= 1/10 work
Work done by 6 men and 8 boys in 14 days= 1 work
Work done by 6 men and 8 boys in 1 day= 1/14 work
Now,
(8 men and 12 boys)=1/10 ....Equation (1)
(6 men and 8 boys)=1/14 .... Equation (2)
Solving Equation (1) and (2), we get
Man=1/140 and Boy=1/280
So, 1 man can alone to finish the work=140 days
1 Boy can alone to finish the work=280 days
