\n" ); document.write( "Hi
\n" ); document.write( "A and B had some cards. After A lost 68 cards to B the ratio of cards that A and B had were 3:8 respectively. When B lost 126 cards to A the ratio of cards that A and B had were 2:3 respectively.
\n" ); document.write( "How many cards did A have at first.
\n" ); document.write( "Thanks
\n" ); document.write( "
Let original number A and B had, be A and B, respectively
\n" ); document.write( "After A lost 68 cards to B, A had A - 68 remaining, and B then had, B + 68
\n" ); document.write( "We then get:
\n" ); document.write( "16A - 6B = 1,496 ---- Multiplying eq (i) by 2 ---- eq (iii)
\n" ); document.write( " 9A - 6B = - 870 ---- Multiplying eq (ii) by 3 --- eq (iv)
\n" ); document.write( " 7A = 2,366 -------- Subtracting eq (iv) from eq (iii)
\n" ); document.write( "Original number A had, or \n" ); document.write( "
\n" );
