उत्तर
Rate (R) = 8% p.a.
Period (T) = 5 years
Interest (I) = ₹12000
(i) ∴ Sum = `("I"xx100)/("R"xx"T")`
`=₹(12000xx100)/(8xx5)`
= ₹30000
(ii) Rate (R) = 10% p.a.
Time (T) = 2 years
Principal (P) = ₹30000
Interest for the first year = `"PRT"/100`
`=₹(30000xx10xx1)/100`
= ₹3000
∴ Amount after one year = ₹30000 + 3000
= ₹33000
Principal for the second year = ₹33000
Interest for the second year =`(33000xx10xx1)/100`
= ₹3300
∴ Compound Interest for two years
= ₹3000 + 3300
= ₹6300
