Question

interest= Rs. 150.30, rate= 3%, time= 8 years. Find principal

Answer 1

Solution :

Principal = p

simple interest ( I ) = Rs 150.30

rate of interest ( r ) = 3%

time ( t ) = 8 years

( ptr )/100 = I

=> p = ( I × 100 )/tr

=> p = ( 150.30 × 100 )/( 8 × 3 )

=> p = 15030/( 8 × 3 )

= 626.25

Therefore ,

Principal ( p ) =Rs 626.25
