Sumiya · Answer

Total 100
Couple with one child =20
Remaining child =100_20=80
Couple with two child =45%
Remaining =80×45/100=36
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.
