Dear SajjadAhmad, (A) 0.07a
(B) 0.57a
(C) 0.7a
(D) 1.75a
(E) 17.5a
I'm happy to respond.
Not very challenging--basically, this question is asking whether we know how to divide decimals.
\(b = \frac{0.35}{0.20}a = \frac{3.5}{2}a = 1.75a\)
OA = (D)
Does all this make sense?

0.35a = 0.2b
or b = 0.35a/0.2 = 1.75a
Option D
or b = 0.35a/0.2 = 1.75a
Option D
