A is 3 years older to B and 3 years younger to C, while B and D are twins. How many years older is C to D?
Answer: Option
Explanation:
Since B and D are twins, so B = D.
Now, A = B + 3 and A = C - 3.
Thus, B + 3 = C - 3 
D + 3 = C-3 C - D = 6.

@All.
Here's my explanation for the solution.
> A is 3 years older to B
and [A is] 3 years younger to C (careful here, not to read B is 3 years younger than C)
So, A = 10 and B = 7
And A = 10 and C = 13.
Hence the difference between C and B (twin of D) is 13 - 7.
which is 6.
