Explanation:

Ur Answer:-

2,400

Ur Explanation:

Principle = ₹2000 ; Time = 2 yrs & Rate = 10%.

\begin{gathered} \frac{p \times r \times t}{100} \\ \\ = \frac{2000 \times 2 \times 10}{100} = 20 \times 2 \times 10 =rs \: 400\end{gathered}100p×r×t=1002000×2×10=20×2×10=rs400

Therefore, S.I. = Rs. 400.

Total Amount = principal +si

=₹ (2000+400)

=₹2400.

Hence,

the total amount is ₹ 2,400.
