b. 6
c. 5
d. 8​

Answer 1

Step-by-step explanation:

Let age of B be “x” years.

Since, A is 4 years older to B.

Therefore, age of A = (x+4) years

Since A is 4 years younger to C, it means C is 4 years older to A

Therefore, age of C = Age of A + 4

=[(x+4)+4] years = (x+8) years

Since B and D are twins

Therefore, age of D = age of B = x years

Difference between ages of C and D =[(x+8)-x] years= 8 years

Therefore, C is 8 years older to D

so answer is d option
