Answer:
P= 4000
R= 5% p.a.
Step-by-step explanation:
Amount in 2 years = Rs 4400
Amount in 3 years. = Rs 4600
Therefore Interest in 1 year = Rs(4600-4400)
=Rs 200
Therefore Interest in 2 years = Rs (200 X 2)
= Rs 400
Therefore principal = Amount - Interest
= Rs(4400-400)
= Rs 4000
Therefore let rate of interest be = x % p.a
200 = 4000 * 1 * x / 100
Therefore x = 5
Therefore Rate % per annum = 5 % per annum
Ans. Principal = Rs 4000
Rate = 5% per annum
