X/Y=96.12 --> Y=X/96.12 --(1)

X-Y(96.12)=9 --(2)

No solution by using (1) and (2)â€¦.

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.

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
