DData inadequate

Correct answer is: Data inadequate

Explanation:

The ratio of the earnings of A and BB is 4:7

Let Earnings of A=4k

Earnings of B=7k

Earnings of A now becomes 4k+\frac{1}{2}​×4k=4k+2k=6k

Earnings of B now becomes 7k−\frac{1}{4}​×7k=\frac{3}{4}​×7k=\frac{21k​}{4}

Now ratio of earnings are \frac{6}{\frac{21}{4}}​=\frac{24}{21}​=\frac{8}{7}

Hence the Data is Inadequate.
