Given : A colony have 2/5 family read samad & 3/4 read samaj if 50 family don't read any paper & 125 family read both paper
To find : Total Families
Solution :
Let say Total Family = 20F
Read Samad = (2/5) 20F = 8F
Read Samaj = (3/4) 20F = 15F
Read Both = 125
Read none = 50
Total = Samad + Samaj - Both + None
=> 20F = 8F + 15F - 125 + 50
=> 3F = 75
=> F = 25
Total Family = 20F = 20 * 25 = 500
there are total 500 Families
