The total amount of ₹ 15,02,000 is divided among A, B, and C in the ratio $5:7:85:7:8$5:7:8.

1. Calculating Individual Shares:
   • Total parts = $5+7+8=205\; +\; 7\; +\; 8\; =\; 20$5+7+8=20
   • Amount for $AA$A: $A=\frac{5}{20}\times 15,02,000=₹3,75,500A\; =\; \backslash frac\{5\}\{20\}\; \backslash times\; 15,02,000\; =\; ₹\; 3,75,500$A=205​×15,02,000=₹3,75,500
   • Amount for $CC$C: $C=\frac{8}{20}\times 15,02,000=₹6,00,800C\; =\; \backslash frac\{8\}\{20\}\; \backslash times\; 15,02,000\; =\; ₹\; 6,00,800$C=208​×15,02,000=₹6,00,800
2. Calculating Simple Interest:
   • For A (4% for 2 years):

     $A_{}=\frac{P\times r\times t}{100}=\frac{3,75,500\times 4\times 2}{100}=₹3,006\backslash text\{SI\}\_A\; =\; \backslash frac\{P\; \backslash times\; r\; \backslash times\; t\}\{100\}\; =\; \backslash frac\{3,75,500\; \backslash times\; 4\; \backslash times\; 2\}\{100\}\; =\; ₹\; 3,006$SIA​=100P×r×t​=1003,75,500×4×2​=₹3,006

   • For C (6% for 5 years):

     $C_{}=\frac{P\times r\times t}{100}=\frac{6,00,800\times 6\times 5}{100}=₹1,80,240\backslash text\{SI\}\_C\; =\; \backslash frac\{P\; \backslash times\; r\; \backslash times\; t\}\{100\}\; =\; \backslash frac\{6,00,800\; \backslash times\; 6\; \backslash times\; 5\}\{100\}\; =\; ₹\; 1,80,240$SIC​=100P×r×t​=1006,00,800×6×5​=₹1,80,240

Conclusion: The simple interest obtained by A is ₹ 3,006, and by C is ₹ 1,80,240.
