Answer:
Step-by-step explanation:
let days of men= x
let days of women be = y
in one day= 1/x and 1/y
according to Q
8/x+ y/12= 1/10
x/6+ y/8= 1/14
let 1/x= a
let 1/y= b
so,
8a+ 12b= 1/10
6a + 8b = 1/14
elimination method
48a+ 72b = 3/5
48a + 64b= 4/7
- - -
___________
8b = 1/35
b= 1/280
y= 280days
8a + 12/280=1/10
8a= 2/35
a= 1/140
x= 140days
