Question

Find the simple interest on a sum of Rs.12000 at the rate of 5% for 3 years​

Answer 1

Solution:

Principal = Rs. 12000

Rate = 5%

Time = 3years

Simple Interest = ?

$\tt{S.I. \: = \frac{P \times R \times \: T}{100}}$

$\sf{ = \frac{12000 \times 5 \times 3}{100} }$

$\sf{ = 120 \times 5 \times 3}$

$\sf{ = 600 \times 3}$

$\tt{=Rs. \: 1800}$

Therefore, simple interest is Rs. 1800

A = P + SI

P = A - SI

SI = A - P
