Answer 2

Answer:

₹ 6400

Step-by-step explanation:

Given,

Principal, p = ₹ 5120

Rate of intrest, r = 12½ % = 25/2 % p.a

Time, t = 2 yrs.

To find the amount.

We know that,

Amount, a = Principal + S.I

So, let's find S.I first.

Also, we know that,

S.I = p × r × t/100

Substituting the values, we get,

=> S.I = 5120 × 25/2 × 2/100

=> S.I = 1280

Therefore, we will get,

=> a = 5120 + 1280

=> a = 6400

Hence, the required amount is ₹ 6400.
