For finding ratio of B to F, we need ratio of A or B to E or F
Statement 1 - We know the ratio of D to E. But there is nothing known about relation of A, B with C, D
Not sufficient

Statement 2 - Ratio of A to D is given but nothing is mentioned about relation of either A, B or C, D to E,F
Not sufficient

Combing both, we know the ratio of D to E and ratio of A to D. We can find the ratio of A to E. A is related to B and F is related to E. We can find the ratio of B to F using both statements.

Option C

\(\frac{A}{D} = \frac{5}{1}\) , \(\frac{D}{E} = \frac{1}{2}\)
Multiplying both fractions, \(\frac{A}{E} = \frac{5}{2}\).

\(\frac{A}{B} = \frac{7}{3}\), \(\frac{B}{A} = \frac{3}{7}\)
\(\frac{A}{E} = \frac{5}{2}\)
Multiplying the 2 fractions, we get \(\frac{B}{E} = \frac{15}{14}\) - (i)

\(\frac{E}{F} = \frac{4}{1}\) - (ii)

Multiplying (i) and (ii), we get \(\frac{ B}{F} = \frac{30}{7}\)
