B1,200
C1,300
D1,400
Answer & Solution
Correct answer: B. 1,200
1. P = 5000, R = 8 आणि T = 3 सह P x R x T / 100 हे सूत्र वापरा.
2. एका वर्षाचे व्याज 5000 चे 8 टक्के = 400 आहे.
3. तीन वर्षांसाठी ते 400 x 3 आहे.
4. म्हणून सरळव्याज 1200 आहे.
5. परतफेडीची रास 5000 + 1200 = 6200 होईल, परंतु प्रश्नात फक्त व्याज विचारले आहे.
