Let no. Of men be x And woman be y A/Q 2y+5x=4 take as equation 1 3y + 6x= 3 take as equation 2 Multiply equation 1 by 3 and equation 2 by 2 Therefore 6y-6y+15x-12x=12-6 3x= 6 X= 6/3 X= 2 Men takes 2 days ( answer) Now apply x in equation 1 We get 2y= 6 Y = 6/2 = 3 Therefore Woman takes 3 days ( answer)

And woman be y
A/Q
2y+5x=4 take as equation 1
3y + 6x= 3 take as equation 2
Multiply equation 1 by 3 and equation 2 by 2
Therefore 6y-6y+15x-12x=12-6
3x= 6
X= 6/3
X= 2
Men takes 2 days ( answer)
Now apply x in equation 1
We get
2y= 6
Y = 6/2
= 3
Therefore
Woman takes 3 days ( answer)
