Couple with two child =45%

Couples with three or more children =80_36=44%

Nishant · Answer

Consider there are 100 couples in total.
Now, 20 have 1 child.
45% of remaining, i.e. 45% of 80=36 have 2 children.
Out of total, there are 100-56= 44 couples with 3 or more children.
Thus, 44% couples have 3 or more children.
