(a).
\n" ); document.write( "Now according to the given conditions:
\n" ); document.write( "x/7 = 4/1
\n" ); document.write( "x = 4y
\n" ); document.write( "Total number of stickers in the box is: 185
\n" ); document.write( "Therefore:
\n" ); document.write( "x + y = 185
\n" ); document.write( "x = 148
\n" ); document.write( "y = 36
\n" ); document.write( "Now let n number of blue stickers took from the box.
\n" ); document.write( "(148-n)/37+n = 3/1
\n" ); document.write( "solving this equation:
\n" ); document.write( "n = 37
\n" ); document.write( "Therefore:
\n" ); document.write( "Number of blue stickers = 111
\n" ); document.write( "Number of green stickers = 148
\n" ); document.write( "740 stickers in total
\n" ); document.write( "(b).
\n" ); document.write( "Number of green stickers at first = 37 * 4 = 148
\n" ); document.write( "
\n" ); document.write( "
\n" );
