Question

The interest on the sum of 4 years at 5℅ p.a is 90 . The sum is :

Answer 1

Step-by-step explanation:

Interest (I)=90

Time (T)=4 years

Rate of interest (R)=5%

We know that : I =PTR/100

=>P=(100×I)/TR

=>P = (100×90)/(4×5)

=>P=9000/20=450

The Principle =450

Answer 2

$The \: principal \: = \: 450$
