Correct answer: (B) Rs 300
Difference for 2 years = P(R/100)2 = 4800 × (25/100)2 = 4800 × 0.0625 = Rs 300. Check: SI = 4800×25×2/100 = Rs 2400; CI = 4800×(1.252 − 1) = 4800×0.5625 = Rs 2700; difference = 2700 − 2400 = Rs 300.

सही उत्तर: (B) 300 रुपये
2 वर्षों के लिए अंतर = P(R/100)2 = 4800 × (25/100)2 = 4800 × 0.0625 = 300 रुपये। जाँच: SI = 4800×25×2/100 = 2400 रुपये; CI = 4800×(1.25² − 1) = 4800×0.5625 = 2700 रुपये; अंतर = 2700 − 2400 = 300 रुपये।
