29Ans B
(y - 4)/3 = [x] and y/4 = [x-3]
so by the abv two equations it can be concluded that y is an integer and a multiple of 4..and y-4/3 is also an integer..
so the probable values of x and y
y = 16 4 < x < 5
y = 28 8 < x < 9
y = 40 12 < x < 13
y = 52 16 < x < 17..
so the fourth value
y = 52 16 < x < 17
satisfy both the equation simultaneously
so [x - y] = -36
341You can compress the numbers of steps.
4[x-3] = 4([x]-3) = 4[x]-12. So [x] = 16. and so on.
