Question

7 men and 3 women complete the work together in 10 days 8 men and 2 women complete the same work in 8 days how much work can be done by 10 men in one day​

Answer 1

Answer:

7/40

Step-by-step explanation:

Work done by 7 Men and 3 Women in 1 day = 1/10 --------- (i)

Work done by 8 Men and 2 Women in 1 day = 1/8 ---------- (ii)

Let the work done by 1 Man in 1 day = M

"              "             "       1 Woman   "     = W

Multiplying 2 in eqn (i) and 3 in eqn (ii)

14M + 6W = 1/5

24M + 6W = 3/8

Subtracting eqn (ii) from (i), we get,

-10M = -7/40

∴ 10M = 7/40

∴ Work done by 10 Men in 1 day = 7/40      ←ANSWER

∴ Time taken by 10 Men to complete the work = 40/7 days
