Algebra.Com's Answer #329221 by mathstutor494(120)![]() ![]() You can put this solution on YOUR website! Let there be \"x\" sweets in original bag\r \n" ); document.write( "\n" ); document.write( "Gave 1 to son so remaining are x-1 sweets \n" ); document.write( "1/7 of remaining sweets = (x-1)*(1/7)=> (x-1)/7 \n" ); document.write( " \n" ); document.write( "Hence total sweets given to son \n" ); document.write( "1+((x-1)/7) \n" ); document.write( "(x+6)/7 ...............................(1)\r \n" ); document.write( "\n" ); document.write( "Sweets remaining in the bag after giving to son \n" ); document.write( "x-((x+6)/7) \n" ); document.write( "(6x-6)/7\r \n" ); document.write( "\n" ); document.write( "Out of this he gave 2 sweets to daughter so remaining sweets are \n" ); document.write( "((6x-6)/7)-2 \n" ); document.write( "=(6x-20)/7\r \n" ); document.write( "\n" ); document.write( "Further, he gave 1/7 from remaining lot to his daughter... \n" ); document.write( "((6x-20)/7)*(1/7) \n" ); document.write( "=(6x-20)/49\r \n" ); document.write( "\n" ); document.write( "So total sweets with daughter \n" ); document.write( "((6x-20)/49)+2 \n" ); document.write( "=(6x+78)/49 ..............................(2)\r \n" ); document.write( "\n" ); document.write( "Since the problem specifies that the two children found that they have same number of sweets, so expressions (1) and (2) are equal. \n" ); document.write( "Accordingly\r \n" ); document.write( "\n" ); document.write( "(x+6)/7 = (6x+78)/49 \r \n" ); document.write( "\n" ); document.write( "Solving for x gives value of 36\r \n" ); document.write( "\n" ); document.write( "Ans : 36 sweets there in original bag\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
