Answer 2

Given

principal (p) = RS 1200

Rate of interest (R) =5%pa

Time (t)= 3years

TO FIND

amount

compound interest

Sol

amount = p(1 +R/100)ⁿ

substitute the value of principal ,rate and time

A = 1200 (1+5/100)³

A =1200 (1+1/20)³

A = 1200(21/20)³

A = 1200 ×21/20×21/2 ×21/20

A= 3×21×21×21/20

A =27783/20

rs= 1389.15

compound interest =AMOUNT- PRINCIPAL

CI =A - P

CI = 1389.15 - 1200

CI = 189.15

HENCE

AMOUNT = 1389.15

CI =189.15
