D. a is 5 times b.

E. a is $$\frac{3}{5}$$ of b.

Simplifying the given expression,
$$\frac{(a+2b)}{(17b-2a)}=1$$
Or, a+2b=17b-2a
Or, 3a=15b
Or, a=5*b
Or, a is 5 times b.

Ans. (D)

$$\frac{(a+2b)}{(17b-2a)}=1$$

Or, $$a + 2b = 17b - 2a$$

Or, $$3a = 15b$$

Or, $$a = 5b$$, Answer must be (D)

Simplifying, we have:

a + 2b = 17b - 2a

3a = 15b

a = 5b

So a is 5 times b.
