Old interest = 8% of x New interest = 7.75% of x So the difference in income = (8% -7.75%) of x = 0.25% of x = Rs. 61.50 Now solve: 0.25% of z = 61.50×61.50 xx = 61.50 x = 61.50 × 400 24,600 Answer: (C) Rs. 24,600

Concept Used: Simple Interest (SI) = (Principal × Rate × Time) / 100 Here, time = 1 year. So, difference in income = (P × 8 × 1)/100 - (P × 7.75 × 1)/100 = Rs. 61.50 So, (P × (8 - 7.75)) / 100 = 61.50 => P × 0.25 / 100 = 61.50 => P = (61.50 × 100) / 0.25 => P = 6150 / 0.0025 => P = 24,600 --- Final Answer: (C) Rs. 24,600
