Actually \(\frac{a}{b}=\frac{3}{7}\) AND \(\frac{c}{d}=\frac{3}{7}\)
In the first one, a is a multiple of 7 and b of 3
In the second one, c is a multiple of 7 and d of 3.
Now, a=14 and d=6 and which in QA is 21
Then, c=21 and d= 9 so in QB is 30 So the answer is B.
However, a =35 and b=15 and QA is 50
c=7 and d = 3 and QB is 10 So the answer is A. Not sufficient information to have a clear and definitive answer.
The OA is D.
Hope this helps
