Question

find:
P = ₹25000
A=₹27250
T = 3 years. S.I=(?)
R = (?)​

Answer 1

Answer:

find:

find:P (Principal)= ₹25000

A (Amount)=₹27250

T /N (Number of years) = 3 years.

S. I. ( Simple Interest) =(?)

R (Rate of interest)= (?)

Simple Interest = Amount - Principal

Simple Interest = 27250 - 25000

Simple Interest = 2250

Simple Interest = RS 2250

Simple Interest = P × R × N /100

2250 = 25000 × R × 3 / 100

2250 = 250 × R × 3

2250 = 750 × R

R = 2250 / 750

R = 3

Ans; The rate if interest 3% per annum

Answer 2

Answer:

The simple interest earned is Rs. 2,250.

The rate of interest is 3% p.a.

Step-by-step explanation:

The simple interest earned on a principal (P) is the difference between the final amount (A) and the principal.

Given:

P = Rs. 25000

A = Rs. 27250

t = 3 years.

The simple interest earned is:

$SI=A-P=27250-25000=2250$

Thus, the simple interest earned is Rs. 2,250.

The formula to compute the simple interest is:

$SI=\frac{P\times r\times t}{100}$

Compute the rate of interest charged as follows:

$SI=\frac{P\times r\times t}{100}\\2250=\frac{25000\times r\times 3}{100}\\ r=\frac{2250\times100}{25000\times 3}\\=3$

Thus, the rate of interest is 3% p.a.
