Question

At what rate will Rs. 1,500 yield Rs. 25 simple interest in 8 months ?​

Answer 1

Answer:

P=1500

T=8 month=2/3years

simple interest

let rate of interest be x

SI=PTR/100

25=1500.x.2/3÷100

10x=25

x=2.5%

so rate of interest is 2.5%

Answer 2

The rate of interest is 2.5%

Step-by-step explanation:

Principal = Rs.1500

Simple interest = 25

Time =$8 months = \frac{8}{12} year$

$Si = \frac{P \times T \times R}{100}$

$25 = \frac{1500 \times \frac{8}{12} \times R}{100}$

$\frac{25 \times 100}{1500 \times \frac{8}{12}}=R$

2.5 = R

Hence The rate of interest is 2.5%
