दिलेले आहे:

मुद्दल = ₹4,800

रास = ₹5,043

मुदत = 2 वर्षे

वापरलेले सूत्र:

A = P(1 + r/100)t

गणना:

प्रश्नानुसार,

A = P(1 + r/100)t

⇒ 5043 = 4800 × (1 + r/100)2

⇒ (1 + r/100)2 = (5043/4800)

⇒ (1 + r/100)2 = (1681/1600)

⇒ (1 + r/100)2 = (41/40)2

⇒ (100 + r)/100 = 41/40

⇒ (100 + r)/5 = 41/2

⇒ 200 + 2r = 205

⇒ 2r = (205 – 200)

⇒ 2r = 5

⇒ r = 2.5%

∴ पर्याय (३) योग्य आहे.
