Let their ages be (x)
\n" ); document.write( "Girls age =half(x), which x represent her mother
\n" ); document.write( "mothers age =x-5
\n" ); document.write( "dads age = total age - total sum of the ages of the girl and her mothers age.
\n" ); document.write( "therefore, total ages is 100
\n" ); document.write( "so, 1/2x + x - 5 + x = 100
\n" ); document.write( " x + 2x - 10 + 2x = 200
\n" ); document.write( " 5x = 190
\n" ); document.write( " x = 38
\n" ); document.write( " .
\n" ); document.write( " . . Girls age is 1/2x
\n" ); document.write( " 1/2(38) = 19yrs
\n" ); document.write( " Mothers age is = x-5
\n" ); document.write( " = 38-5
\n" ); document.write( " = 33yrs
\n" ); document.write( " Dads age is = 100 - (19 + 33)
\n" ); document.write( " = 100 - 52
\n" ); document.write( " = 47yrs \n" ); document.write( "
\n" );
