Rs.13680 is the answer.
Step-by-step explanation:-
Given-
•Principal (P) = Rs.57,000
•Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
•Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680
