Junaid was 28 when his daughter Hafsa was born.
\n" ); document.write( " If junaid is now three times as old as hafsa, how many years ago was he 5 times as old as Hafsa?
\n" ); document.write( ":
\n" ); document.write( "From the information given we know Jun is 28 yrs older than Haf, therefore
\n" ); document.write( "j = h + 28
\n" ); document.write( ":
\n" ); document.write( "Jun is now 3 times as old as h, therefore
\n" ); document.write( "j = 3h
\n" ); document.write( "replace j with (h+28)
\n" ); document.write( "h + 28 = 3h
\n" ); document.write( "28 = 3h - h
\n" ); document.write( "28 = 2h
\n" ); document.write( "h = 28/2
\n" ); document.write( "h = 14 yrs is Haf's present age
\n" ); document.write( "then
\n" ); document.write( "14 + 28 = 42 yrs is Jun's present age
\n" ); document.write( ":
\n" ); document.write( "\"how many years ago was he 5 times as old as Hafsa?\"
\n" ); document.write( "let y = no. of yrs ago that this is true
\n" ); document.write( "42 - y = 5(14-y)
\n" ); document.write( "42 - y = 70 - 5y
\n" ); document.write( "-y + 5y = 70 - 42
\n" ); document.write( "4y = 28
\n" ); document.write( "y = 28/4
\n" ); document.write( "y = 7 yrs ago Jun was 5 time Haf's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this checks out
\n" ); document.write( "7yrs ago:
\n" ); document.write( "j = 35
\n" ); document.write( "h = 7; confirms our solutions
\n" ); document.write( " \n" ); document.write( "
\n" );
