Question

Please answer the 13th one​

Answer 1

Answer:

a) part

3m + 4w = 1/28, 4m + 6w = 1/20 …..fraction of a pond per day

84m + 112w = 1/1 , 80m + 120w = 1/1….one whole pond per day

84m + 112w = 80m + 120w

4m = 8w

m = 2w

two women = one men

b) part

(3M + 4W) x 28 = (4M + 6W) x 20

21M + 28W = 20M + 30W

1M = 2W

Now,

3M + 4W = 28 Days

6W + 4W = 28 Days

10W = 28 Days

Now,

7M + 6W = ?

7M = 14W

14W + 6W = @20W

thus, 20W = 14 days.
