\n" ); document.write( " Let us say the racquets sold at lower rate = x
\n" ); document.write( " Let us say the racquets sold at higher rate = y\r
\n" ); document.write( "\n" ); document.write( " Now, we will frame equations. The total racquets sold = 200
\n" ); document.write( " So x + y = 200 ...... (1)
\n" ); document.write( " In all the total amount received = $4800
\n" ); document.write( " So 18x + 33y = 4800 ...... (2)
\n" ); document.write( "(1)*18, we get
\n" ); document.write( " 18x + 18y = 3600 ...... (3)
\n" ); document.write( " (2)-(3), we get
\n" ); document.write( " 15y = 1200
\n" ); document.write( "So Y = \"1200%2F15\" = 80
\n" ); document.write( "Substituting the value of y in the eq.(1), we get
\n" ); document.write( " x + 80 = 200 i.e x = 200-80 = 120\r
\n" ); document.write( "\n" ); document.write( "So the no. of racquets sold at $18 = 120
\n" ); document.write( " the no. of racquets sold at $33 = 80 Answer.\r
