Two numbers are such their diff ,their sum and their product are in the ratio 1;7:24.the product of the numbers is
a) 24 b) 36 c) 48
d) 60

• x+y/x-y=7/1
  7x+7y=x-y
  6x=8y
  3x=4y
  
  also, x-y/xy=1/24
  24x-24y=xy
  8(3x)-24y=xy
  replace 3x by 4y
  32y-24y=xy
  8y=xy
  x=8
  y=(3/4)*8=6
  xy=8*6=48 ans

• Two numbers are such their diff ,their sum and their product are in the ratio 1;7:24 by hit and trial method
  multiply each by 2 we get 2:14:48
  the number which satisfy this is 6,8
  whose difference is 8-6=2
  sum is 8+6=14
  product is 8*6=48
