प्रश्न
Find the amount and the compound interest on ₹ 16,000 for 3 years at 5% per annum compounded annually.
उत्तर
Principal (P) = ₹16,000
Time (t) = 3 years
Rate (r) = 5%
`"Amount" = "Principal"xx(1+R/100)^n`
`= 16000xx(1+5/100)^3`
`= 16000xx(21/20)^3`
`=16000xx21/20xx21/20xx21/20`
= ₹18,522
C.I. = Amount − Principal
= ₹18,522 − ₹16,000
= ₹2522
