Let the amount of annual installment be 'P'
The amount for 1 year,
⇒ \(P+\frac{P×1×8}{100}=\frac{27P}{25}\)
The amount for 2 years,
⇒ \(P+\frac{P×2×8}{100}=\frac{29P}{25}\)
The amount for 3 years,
⇒ \(P=\frac{P×3×8}{100}=\frac{31P}{25}\)
From the given question,
∴ \(\frac{27P}{25}+\frac{29P}{25}+\frac{31P}{25}=2240\)
⇒ \(\frac{27P+29P+31P}{25}=2240\)
⇒ \(\frac{112P}{25}=2240\) ⇒ \(P=\frac{2240×25}{112}=500\)
Hence, option A is the correct answer.The correct option is (A): Rs.500
