Answer 2

The amount will be ₹ 2600.

Step-by-step explanation:

To find the amount, we need to calculate the simple interest and then add it to the principal.

In the given question: Principal, P = ₹ 2000, Rate of interest, R = 10% p.a

and the time period of investment, T = 3 years

Now, using the formula for Simple Interest, SI = $\frac{(P\times R \times T)}{100}$

= ₹ 2000$\times$10$\times$3/100

= ₹ 600

Hence, the amount = P + SI = ₹ 2000 + ₹ 600 = ₹ 2600
