Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
मुद्दल 1 (P₁) = 1760 रुपये
दर 1 (R₁) = 6% प्रतिवर्ष
मुद्दल 2 (P₂) = 2240 रुपये
दर 2 (R₂) = 9% प्रतिवर्ष
एकूण व्याज = 1536 रुपये
वापरलेली संकल्पना:
सरळ व्याज (SI) = मुद्दल (P) × दर (R) × वेळ (T) / 100
वापरलेले सूत्र:
SI₁ = P₁ × R₁ × T/100
SI₂ = P₂ × R₂ × T/100
एकूण व्याज = SI₁ + SI₂
गणना:
SI₁ = 1760 × 6 × T/100
⇒ SI₁ = 105.6T
SI₂ = 2240 × 9 × T/100
⇒ SI₂ = 201.6T
एकूण व्याज = SI₁ + SI₂
⇒ 1536 = 105.6T + 201.6T
⇒ 1536 = 307.2T
⇒ T = 1536 / 307.2
⇒ T = 5
∴ मुदत 5 वर्षे आहे.
