A)
\n" ); document.write( "Let one number be x
\n" ); document.write( "and the other number be y
\n" ); document.write( "We know that y = 3x
\n" ); document.write( "Reciprocal of x = 1/x
\n" ); document.write( "Reciprocal of y = 1/y
\n" ); document.write( "Sum of reciprocal = 1/6\r
\n" ); document.write( "\n" ); document.write( "So, we have
\n" ); document.write( "1/x + 1/y = 1/6
\n" ); document.write( "Now substituting 3x in place of y we get :
\n" ); document.write( "1/x+1/3x = 1/6
\n" ); document.write( "(3+1)/3x = 1/6
\n" ); document.write( "4/3x = 1/6
\n" ); document.write( "4X6=1X3x
\n" ); document.write( "24=3x
\n" ); document.write( "x=24/3
\n" ); document.write( "x=8
\n" ); document.write( "y=3x=3X 8 =24
\n" ); document.write( "Answer: The two numbers are 8 and 24.\r
\n" ); document.write( "\n" ); document.write( "B)
\n" ); document.write( "Let us assume the number to be x. We can write the information given in the question as the following equation :
\n" ); document.write( "1x/3 - 3x/4 = 15
\n" ); document.write( "(4x-9x)/12 = 15
\n" ); document.write( "-5x/12 = 15
\n" ); document.write( "-5x = 15 X 12
\n" ); document.write( "-5x = 180
\n" ); document.write( "x = 180/-5
\n" ); document.write( "x = -36
\n" ); document.write( "Answer: The number is -36
