Question

. A certain amount of money amounts to ₹5500 in 2 years and to ₹5750 in three years. Find the principal and rate of interest
​

Answer 1

Answer:

Principle = 5000Rs

Rate = 5%

Step-by-step explanation:

Simple interest = principal * rate * time/100

Interest of one year = 5750-5500 = 250

then principle = 250 x 100/R*i

Principle = 25000

i = PRT/100

for first two years interest = 25000 x 2/100

interest = 500

principle = amount - interest

= 5500-500 = 5000

Principle = 5000

Rate = 1 x 100/Pt

R = 500 x 100/5000 x 2

Rate = 5%

Answer 2

Answer:

principle: 5000

rate of interest: 5%

Step-by-step explanation:

SI:P×R×T÷100

Interest of first year : 5750-5500=250

then the principle: 250×100=25000

SI:P×R×T÷100

For first two years interest : 25000×2/100

=500

Principle:Amount- Interest

=5500-500

=5000

Rate of interest:500×100÷5000×2

=5%
