- by hit and trial method:
12-6=6=4+(12/6) - 9 years agoHelpfull: Yes(13) No(4)
- according to the given condition
x-y=4+(x/y)
we need to work with the options here.
subs x = 12 first
12-y=4+(12/y)
solving this eq, we get y=6,2 so the number x will be 12 with y = 2,6

- somthng wrong
- 9 years agoHelpfull: Yes(2) No(0)
- x-y=x/y+4
so x=12 - 9 years agoHelpfull: Yes(2) No(5)

How many different integers can be expressed as the sum of three distinct numbers from the set{13,10,23,28,33,36,43,48}?
A circle has 29 points arranged in a clockwise manner numbered from 0 to 28 . A bug moves clockwise around the circle according to the following rule.If it is at a point i on the circle, it moves clockwise in 1 second by (1+r) places , where r is the remainder (possibly 0) when i is divided by 17. Thus it is at position 5 , it moves clockwise in one second by (1+5) places to point 11. similarly ,if moves (1+11) or 12 places to point 11 in one second.
If it starts at point 0,at what point will it be after 2012 seconds?
