let x = the original consumption.
\n" ); document.write( "let y = the original price.
\n" ); document.write( "the expenditure is therefore equal to x*Y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you raise the new price by 20%, then the new price is equal to 1.2 * y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1.2 * y is the same as 6/5 * y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in order to keep the expenditure the same, the original consumption needs to be divided by 1.2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divided by 1.2 is the same as multiplying by 1/1.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "multiplying by 1/1.2 is the same as multiplying by 5/6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the original price is multiplied by 6/5, the original consumption has to be multiplied by 5/6 in order to keep the total expenditure the same.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "expenditure = x * y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "expenditure = 5/6 * x * 6/5 * y = x * y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the expenditure remains the same.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the problem is stated as shown below:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Price of sugar is increased by 20% if the expenditure on sugar has to be kept the same as earlier the ratio between the reduction in consumption and the original consumption is?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "they are looking for the ratio between the reduction in consumption and the original consumption.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the original consumption is x and the reduced consumption is 5/6 * x, then the reduction in consumption is 1/6 * x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the ratio between the reduction in consumption and the original consumption is therefore 1/6 * x / x which results in 1/6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
