Read Solution (Total 2)
-
- 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
