Answer» Work DONE by 4 men and 6 women in 1 day = 1/8 Work done by 3 men and 7 women in 1 day = 1/10 LET 1 man does m work in 1 day and 1 woman does W work in 1 day. The above equations can be written as 4m + 6w = 1/8 ---(1) 3m + 7w = 1/10 ---(2) Solving equation (1) and (2) , we get m=11/400 and w=1/400 Amount of work 10 women can do in a day = 10 × (1/400) = 1/40 IE, 10 women can complete the work in 40 days Work done by 4 men and 6 women in 1 day = 1/8 Work done by 3 men and 7 women in 1 day = 1/10 Let 1 man does m work in 1 day and 1 woman does w work in 1 day. The above equations can be written as 4m + 6w = 1/8 ---(1) 3m + 7w = 1/10 ---(2) Solving equation (1) and (2) , we get m=11/400 and w=1/400 Amount of work 10 women can do in a day = 10 × (1/400) = 1/40 Ie, 10 women can complete the work in 40 days |
