Solution

The correct option is D 7
Let x be the number of women and y be the number of men.
Total number of members on the board = x+y=10...(1)
As per given condition, there are 4 women more than men
x=y+4
Putting the above equation in equation 1 we get
2y=6; y=3
Putting y=3 in equation 1
we get x=7
There are total 7 women on the board.
