Given:
a/b = 7/11
b/c = 12/17
Concept used:
If ratio a : b1 and b2 : c has b1 = b2 = b
Then, the ratio can be written as a : b : c
Calculation:
We have b common in both fractions
Equating b by multiplying a/b with 12 and b/c with 11
a/b = (7/11) × 12 = 84/132
b/c = (12/17) × 11 = 132/187
So, a : b : c = 84 : 132 : 187
Now, a + b = 84 + 132 = 216 units
And, b + c = 132 + 187 = 319 units
⇒ (a + b)/(b + c) = 216/319
Hence, the value of 
(a + 
b)/(b + c)
 is 216/319.

Simplify the 3 equations to the form a:b:c

a/b =7/11 =84/132

b/c =12/17 =132/187

Hence,
a:b:c = 84:132:187

Thus, (a+b)/(b+c)
=(84+132)/(132+187)
=216/319

Thus, Option D) 216/319 is correct
