Answer 1

Answer:

3000

Step-by-step explanation:

Amount(A1) = Rs.4500,

t1= 2 years

Amount(A2) = Rs.6750,

t1= 4 years

Let the Rate % = R %

Principal = Rs. P

According to the question,

Case1: 4500

=p(1+R100)2...........1

Case2: 6750

=p(1+R100)4...........1

By dividing eq. 2, by eq. 1

67504500=(1+R100)2

32=(1+R100)2..........3

From eq. 1

4500=P×32

P= Rs.3000

Hence,Required principal

=Rs. 3000
