1.	The cmpound interest on rs.4000 at the rate of 10% for 2 years is
Answer» CI = PRINCIPAL (1 + rate/100)^t - Principal = 4000 (1 + 10/100)^2 - 4000 = 4000 ( 1 + 1/10) ^2 - 4000 = 4000 ( 11/10) 2 - 4000 = 4000 * 11/10 * 11/10 - 4000 = 4840 - 4000 = 840

Answer»

CI = PRINCIPAL (1 + rate/100)^t - Principal

= 4000 (1 + 10/100)^2 - 4000

= 4000 ( 1 + 1/10) ^2 - 4000

= 4000 ( 11/10) 2 - 4000

= 4000 * 11/10 * 11/10 - 4000

= 4840 - 4000

= 840
