Z repaid ₹10,920 after 4 years at 10% per annum simple interest. How much money did he borrow?
Z ने 4 वर्ष बाद 10% वार्षिक साधारण ब्याज सहित 10.920 रुपेए चुकाए| उसने कितने रुपेए उधार लिए थे?
Detailed Solution & Logic
Correct Answer:
Rs 7,800
Use the simple interest relation:
$A = P \left(1 + \frac{RT}{100}\right)$
Given:
Amount $A = 10920$, Rate $R = 10%$, Time $T = 4$ years
Substitute:
$10920 = P \left(1 + \frac{10 \times 4}{100}\right)$
$10920 = P (1 + 0.4)$
$10920 = 1.4P$
So,
$P = \frac{10920}{1.4} = 7800$
Final Answer: ₹7,800
