Date:2012-02-23 12:59:02 Charles is twice as old as william. Four years ago Charles was 3 times as old as william.How old is each now? Let age of Charels = C and age of William = W As per 1st condition, C = 2W ...........(1) as per 2nd condition, (C - 4) = 3(W - 4) put the values from (1) and we get; 2W - 4 = 3(W - 4) solve parenthesis and we get; 2W - 4 = 3W - 12 2W - 3W = -12 + 4 -W = -8 multiply both side by (-1) and we get W = 8 Put the value of 8 in (1) and we get C = 2 * 8 = 16 so age of Charels = 16 years and age of William = 8 years Hope this will help you....
