X/Y=96.12 --> Y=X/96.12 --(1)
X-Y(96.12)=9 --(2)
No solution by using (1) and (2)….
Any other approach?

x =k*y + 9
x/y = k +9/y
96.12 - 9/y = k where k is a +ve int
So plug in vals you get B

Given x = y*m +9.
x/y = m + 9/y
or 96.12 = 96 +0.12 = m + 9/y
where m =96, and 9/y = 0.12
i.e. 9/y = 0.12
or y = 9/0.12 = 900/12 = 75.
Answer: D

Guys, one more simple funda. 5/2= 2.5 now .5 x2 =1 is the remainder 25/4 = 6.25 now .25x4=1 is the remainder 32/5=6.4 now.4x5 = 2 is the remainder given x/y = 96.12 and remainder is 9 So .12 X y = 9 hence y= 75

B, Used the same logic as cicerone
First, which value to pick?
.12 multiplied by which value gives you an integer ?
went with 75 and 25
Plugged in 75 , got remainder 9. Answer 75
