प्रश्न
Dhruvika invested money for a period from May 2006 to April 2008 at rate of 12% per annum. If interest received by her is ₹ 1620, find the money invested.
उत्तर
Given, I = ₹ 1620 and R = 12%
Time = From May 2006 to April 2008 = 2 yr
∵ I = `(P xx R xx T)/100`
∴ P = `(I xx 100)/(R xx T) = (1620 xx 100)/(12 xx 2)`
⇒ P = ₹ 6750
Hence, the invested money is ₹ 6750.
