Question

किसी मूलधन का ब्याज 15 वर्षों में उसके मिश्रधन का 3/5 हो जाता है, तो ब्याज की दर निकालिए।​

Answer 1

Step-by-step explanation:

किसी मूलधन का ब्याज 15 वर्षों में उसके मिश्रधन का 3/5 हो जाता है, तो ब्याज की दर निकालिए।​

Given If the interest of a principal becomes 3/5 of its principal in 15 years, find the rate of interest.  

• We know that S.I = Principal x Rate x Time / 100
• According to the question interest is 3/5 of its principal we get
•         3/5 x P = P x R x 15 / 100
• Or 3/5 = R x 15 / 100
• 3 = 15 R / 20
• 15 R = 60  
• Or R = 60 / 15
• Or R = 4 %

Therefore rate of interest is 4%
