Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 7,488.

6 years amount = ₹8256

2 years amount = ₹5952

⇒ SI for 4 years = 8256 − 5952 = ₹2304

SI for 1 years = 230442304\over4 = ₹576

⇒ SI = PRT100PRT\over100

⇒ SI = 576×143576\times{14\over3} = 2688

Principal = 5952 − (576 × 2) = 5952 − 1152 = 4800

Amount = 4800 + 2688 = ₹7,488
