Isn't the statement C/D=9.75 sufficient?

\(\frac{C}{D}=9.75\) <=> \(\frac{C}{D}=9+\frac{3}{4}\) <=> \(C=D(9+\frac{3}{4})\) <=>\(C=D(\frac{39}{4})\)
D is a positive integer so if \(D = 4\) then \(C=39\).
Answer A

Edit : Nevermind, just realized my reasoning is flawed.

\(\frac{C}{D} = 9.75 = \frac{975}{100}\)

Divide numerator/ denominator by 25

\(= \frac{39}{4}\) which gives remainder of 3

Answer = A

Could you check this? If we divide 31/4 we also have a remainder of 3. Therefore this question has two correct answers (A and D).

Thanks

31/4 = 7.75, not 9.75.

CONCEPT: Decimal part x Divisor = Remainder

0.75 D = 3
i.e. D = 4

Now Divisible part of C by D as divisor = 9*D = 9*4 = 36

i.e. The Number C = 36+3 = 39

Answer: Option A
