Answer 2

Answer:

Principal ( P ) = Rs 4000  

Rate of interest ( r ) = 12½ % = 25/2 %  

Duration ( n ) = 3  

Amount ( A ) = P( 1 + r/100 )ⁿ  

A = 4000 ( 1 + 25/200 )³  

A = 4000 ( 1 + 1/8 )³  

A = 4000 × ( 9/8 )³  

A = Rs 5695.31  

Therefore ,  

Compound Interest = A - P  

= Rs 5695.31 - Rs 4000  

= Rs 1695.31
