A sum of ₹ 600 amount to be ₹ 720 in 4 year by simple interest what be its…

Step 1: Calculate the simple interest for 4 years: ₹720 - ₹600 = ₹120.

Step 2: Use the formula for simple interest: SI = (P × R × T)/100.

Step 3: Substitute the values: 120 = (600 × R × 4)/100.

Step 4: Solve for R: R = (120 × 100)/(600 × 4) = 5%.

Step 5: New rate of interest = 5% + 2% = 7%.

Step 6: Calculate the new simple interest: SI = (600 × 7 × 4)/100 = ₹168.

Step 7: New amount = Principal + Interest = ₹600 + ₹168 = ₹768.

हिन्दी उत्तर:

चरण 1: 4 वर्षों के लिए साधारण ब्याज की गणना करें: ₹720 - ₹600 = ₹120।

चरण 2: साधारण ब्याज के सूत्र का उपयोग करें: SI = (P × R × T)/100।

चरण 3: मानों को प्रतिस्थापित करें: 120 = (600 × R × 4)/100।

चरण 4: R के लिए हल करें: R = (120 × 100)/(600 × 4) = 5%।

चरण 5: नई ब्याज दर = 5% + 2% = 7%।

चरण 6: नया साधारण ब्याज गणना करें: SI = (600 × 7 × 4)/100 = ₹168।

चरण 7: नया राशि = मूलधन + ब्याज = ₹600 + ₹168 = ₹768।
