Explanation:

- The total amount Rs63,404 is split between A and B in the ratio 4:7.

- To find individual shares, calculate the parts:

- Total parts = 4 + 7 = 11

- A's share = $\frac{4}{11}\times 63,404=23,038$

- B's share = $\frac{7}{11}\times 63,404=40,366$

- Now, calculate 5 times A's share and 2 times B's share:

- 5 times A's share = $5\times 23,038=115,190$

- 2 times B's share = $2\times 40,366=80,732$

- Find the difference between the two:

- Difference = 115,190 - 80,732 = 34,458

- Option 1: Rs45,384

- Option 2: Rs34,584

- Option 3: Rs34,580

- Option 4: Rs43,458
